The present invention relates to a head support incorporating sound reproduction means. Furthermore, it relates to a system for distributing multi-dimensional effects.
In particular, the invention relates to a head support incorporating sound reproduction means allowing a more reliable perception of sounds recorded with multi-dimensional microphones. These microphones are capable of recording sounds in a reliable way according to their direction, such as front and rear, right and left side, up and down, in order to perceive, when playing, the direction of movement of the sound source with respect to the microphone system used for recording it.
Furthermore, the invention relates to a system of sound reproduction aimed to reproduce desired sequences of sounds and other multidimensional acoustic effects.
The present invention also relates to a microphone that enables a reproduction offering to the listener a more reliable sensation with respect to the real location of the sound sources at the moment of recording, thanks to a head support incorporating loudspeakers or other sound reproduction means.
In particular, the invention relates to a recording system that provides, in a two channel audio reproduction, a perception of the sound in at least six directions of the sound source, such as front and rear, side right and side left, up and down, static or in approaching and moving away directions.
Very high fidelity recordings, for example recorded using binaural microphones, like the systems described in U.S. Pat. No. 5,031,216A or in WO9807299A1, are known.
These audio recordings require sophisticated reproduction devices, such as surround systems or high fidelity headphones, in order to reproduce spatial effects such as the sound source direction or a movement direction of the audio source.
Different kinds of loudspeaker incorporating devices, arranged for propagating audio recordings, in order to let a single user to hear it, providing also a comfortable support for the head, are known. Such devices, also called “musical pillows”, combine the comfort of the headrest with musical entertainment provided by integrated loudspeakers. These devices can be used at home as well as in professional context, i.e. wellness centers, massage centers, waiting rooms, centers of music therapy, etc.
U.S. Pat. No. 8,566,986B1 describes an example of a musical pillow. The device comprises, in particular, a central body fitted with a circular opening arranged to receive the face of the user in prone position and an electronic board for controlling a vibration unit and a rotation unit. The system also comprises two lateral bodies, each of which is equipped with a speaker connected to the electronic board and to the rotation unit. This way, the two lateral bodies can rotate starting from a first position, coplanar with the central body, to a second position, orthogonal with the central body. The system also comprises a control unit for activating through the electronic board the vibration unit and the rotation unit. Input channels for receiving audio data and playing the loudspeakers located in the two lateral bodies are also present.
This device has the advantage to provide a comfortable support for the head of the user, for any sleeping position, while listening. Furthermore, the lateral bodies can be oriented starting from a position of minimum encumbrance where the two lateral bodies are coplanar with the central body. The portal frame allows the user to listen in a sleeping position by placing the central body of the device on a horizontal plane. However, this device is not designed for listening multi-dimensional audio recordings.
FR2877554A1 describes another multifunctional device comprising a rectangular base in elastic material and two lateral walls. Each lateral wall is arranged at the right and left sides of the base and includes a loudspeaker. Furthermore, a cover fabric is used as tension element for the orthogonal positioning of the two lateral walls, with respect to the base. This way, a good stereophonic listening is obtained from the loudspeakers that are orthogonal to the base. The system also comprises a shape-memory rectangular element arranged to house, in a comfortable way, the back of the head of the user. In particular, such device adapts its shape according to the weight of the head of the user.
Generally, the above described systems have the drawback of not providing a listening of the played sound that allows a realistic perception of the conveying direction of the original sound, if the sound source comes from high fidelity recording systems as described in U.S. Pat. No. 5,031,216A and WO9807299A1, above cited.
There are also systems of binaural recording, as described for example in WO96/10884A1, DE2545446A1, U.S. Pat. No. 5,073,936, which give to the recorded sound, when played, a sensation of multidimensionality. However, these systems do not allow perceiving sensations of movement in up-down directions and recognizing sounds coming from a frontal area, in particular if the frontal area is lower than the listener.
It is therefore a feature of the present invention to provide a head support incorporating loudspeakers that makes it possible to obtain a reproduction of the sound, coming from high fidelity recordings, letting the user to perceive the direction of the sound source as far as possible corresponding to the direction of the sound source with respect to a microphone at the time of recording.
It is also a feature of the present invention to provide such a head support incorporating loudspeakers that allows the user to perceive a position of the sound source the closest possible to the position of the sound source at the time of recording with respect to a recording device.
It is also a feature of the present invention to provide such a head support incorporating loudspeakers that can provide an audio sensation of movement corresponding to a direction of movement of a recorded sound source in approaching or moving away with respect to a recording device.
It is another feature of the present invention to provide such a head support incorporating loudspeakers that allows a versatile utilization with respect to user's postures, without affecting a high fidelity listening of the multidimensional recording.
It is also a feature of the present invention to provide such a head support incorporating loudspeakers that, that both permits a multiplicity of postures of the user, and can be used in many application fields.
It is a further feature of the present invention to provide a head support incorporating loudspeakers that combines a multi-dimensional sound diffusion with a listening comfort.
It is a particular feature of the present invention to provide a head support incorporating loudspeakers that can be used by users with different head shapes and weight without affecting the multi-dimensional listening of the sound.
It is still a feature of the present invention to provide a system for distributing multi-dimensional acoustic effects that, when used in combination with the head support incorporating loudspeakers, can provide predetermined sequences of sounds that are perceived as coming from directions selected by the user or by assisting operators.
It is also a feature of the present invention to provide a system of binaural recording that allows, in a stereophonic listening context through the head support incorporating loudspeakers, according to the invention, or through other devices or reproduction systems, to perceive realistically the direction of the approaching/moving away movement of the sound source at the moment of recording.
It is another particular feature of the present invention to provide such a system of binaural recording that allows, in such a stereophonic listening context, an improvement of perception of the sound source if coming from up to down or vice-versa at the time of recording, and, in particular, the perception of sounds that are moving, at the moment of the recording, between a hypothetical listener and the ground.
It is another particular feature of the present invention to provide such a system of binaural recording that allows, in such a stereophonic listening context, an improvement of perception of the sound source if coming from the front, for example sounds that move in front of a hypothetical listener of the real sound when recording.
These and other features are achieved by a head support device incorporating loudspeakers, according to the invention, comprising:
In a possible embodiment, the tweeters have a center that is higher than the listening axis by a predetermined height, set between 0 and 5 cm.
In another possible embodiment, the tweeters have a center that is translated in the longitudinal direction, proximal to the user, by a predetermined distance, set between 0 and 10 cm.
In the first elevation value the tweeters are arranged so that when the user has the head resting on said housing zone the axes of symmetry coincide substantially with the listening axis.
In still another exemplary embodiment, the tweeters and the woofers are oriented in a predetermined direction, and the direction forms an angle with the horizontal plane set between 0° and 45°, preferably the inclination angle is set between 0° and 35°.
In still a further exemplary embodiment, the tweeters and the woofers are oriented in a predetermined direction, and the direction forms an angle with the vertical plane set between 0° and 10°.
This way, maintaining the tweeters in a position set between the above defined positions, the discrimination of the sound between woofers and tweeters, and the orientation of the axis of symmetry of the right and left tweeter with respect to the position of the user's head, allows the user, when the head is on the rest element, to appreciate all the multidimensional sound data as originally recorded.
In the positions where there is coincidence between axes of symmetry of the tweeters and listening axis, the symmetry of the higher frequency of the sounds with respect to the listening axis allows, when listening the audio recordings obtained by high fidelity binaural microphone, detection of the directionality of the sounds taken with the above described systems of recording. This way, the sound perception with respect to the directionality of sound source which is typical of the existing musical pillows is improved. For example, the listening of a sound that moves from up to down or vice-versa, or of a sound that moves frontally with respect to the listener can be improved. In fact, the position of the right and left tweeters coaxial to the listening axis avoids that the tweeters are located higher or lower than the listening axis, thus avoiding to confuse the listening if the sound source moves up to down or vice-versa. Similarly, the position of the right and left tweeters, coaxial to the listening axis, avoids that the tweeters are located further ahead or behind in the longitudinal direction of the listening axis, thus avoiding to confuse the listening if the sound source moves forward or backward with respect to the longitudinal direction. The asymmetrical position of the woofers instead, reproducing lower frequencies, allows a directional separation of the frequency spectrum between low and high, in order to define further the directional information.
In the positions where the two tweeters are oriented in such a way that converge above the listening axis of the user head, it is obtained an improved perception of the sounds that, at time of recording, came from a frontal direction with respect to the microphone system used to acquire it.
Advantageously, the distance between the right and left tweeters is set between 40 and 80 cm. This way, this distance allows forming a region of sound reproduction within the listening space that surround the head of the user, maximizing the fidelity of reproduction.
In an exemplary embodiment, the rest element provides a receiving recess, symmetric to the longitudinal direction, arranged to accommodate a portion of the user's head.
In particular, if the user rests in supine position, the receiving recess is configured to receive the portion of the user face comprising chin, mouth, nose and eyes, in a comfortable way providing a sensation of comfort to the user. In this case, maintaining one of the structures described above, the tweeters are exchanged with each other and the woofers are exchanged with each other. This way, the multi-dimensional effect on the user is kept notwithstanding its face is oriented in an opposite side.
Advantageously, the receiving recess for the face is made of a soft material and breathable, such as latex or another material designed to provide a adaptable to the face of the subject.
If the user rests on the rest element in a prone position, the receiving recess provides a centering region for the back of the head of the user.
In particular, the receiving recess can have a circular cross section, or a semicircular cross section, or other symmetric shape that assists centering the user's head.
Advantageously, if the user rests with the back of the head, a removable insert made of materials with different hardness from each other can be provided. The insert, besides making the support of the head more comfortable, assists centering of the head by providing a reference point for centering the back of the head of the user.
In a further exemplary embodiment of the invention, the rest element is provided with a deformable plastic micro perforated material and a wire for the connection to the right and left loudspeakers.
This way, the presence of the plastic deformable material allows, while the user rests, a correct position of the joints of shoulder and neck avoiding musculoskeletal diseases.
Advantageously, micro perforation has a size comprised between 1 and 5 mm. This way, this size of the holes allows keeping the head of the user always dry assisting the transpiration.
In an exemplary embodiment, it is provided an anti-skid sticker on the surface of the rest element. This way, the presence of the anti-skid sticker makes it possible to arrange the rest element for example on a headrest of an armchair, allowing use in many situations.
In an alternative exemplary embodiment of the invention, it is provided a connecting element for the left and right lateral support elements. In this exemplary embodiment, the presence of the connecting element allows to wear the head support on the head, with the advantage to use it while moving.
Preferably, the connecting element is flexible, thus fitting the user's head and in the meantime it provides a resiliency that avoids its detachment.
In a further exemplary embodiment of the invention, the right and left lateral support elements are connected to each other in order to form a structure that soundproofs the user inside the listening space. This way, the head support can be used, for example during rest or during travels.
Preferably, the right and left lateral support elements and the rest element are made of ergonomic materials selected from the group consisting of: latex, expanded polyurethane, etc.
In an exemplary embodiment of the invention it is provided the connection of the head support to such devices as tablet, smartphone, pc, cd/dvd reader or an Ethernet network for data streaming. A remote control can also be provided by which a user can interact with the above described devices.
In a further exemplary embodiment, sensors on the rest element are provided to interact with the user. Such sensors can measure the movement of the head of the user, as well as the pressure exerted by the user on the rest element. These sensors can detect the status of the user, identifying for example the movement of the head and of the eyes, allowing the interaction with the software contents of the head support. The sensors are also aimed at activating synchronized sound environments through recognition of opening and closing of pages of a book. The sensors can also be configured to interact with the environment light.
In a further exemplary embodiment, five loudspeakers are provided which are located in said listening space, in such a way to form a surround system. Channels can be connected via amplified audio signal or via HDMI. A device for audio transmission, such as a PC, provides audio contents.
In a possible exemplary embodiment, an articulated structure is arranged to support a mobile device, such as a tablet. This way, the user that rest on the rest element can adjust the articulated structure to its preference to maximize experience when using the tablet.
In a further exemplary embodiment of the invention, the rest element has a housing zone for the user's head oriented in a predetermined direction, and the direction forms an angle with the horizontal plane. This way, the inclination of the housing zone allows the user, when the head is on the rest element, to appreciate all the multidimensional sound information as originally recorded.
According to another aspect of the invention, a system of binaural recording of a sound source is provided, comprising:
This way, the sound is collected at the entrance of the channel in the center of the auricle, and not after having crossed an artificial auditory channel as binaural microphone of prior art. This solution avoids distortion and rumbles of the original sound that would happen otherwise when the sound is propagated through the artificial auditory channel.
The fact that the sound collecting face is located in the recess of the auricle, allows the auricle, and in particular the helix of the auricle, to shield sounds such as the ones that come from behind or from above the head. This allows better discrimination of those sounds compared to the sounds coming from the lateral sides.
Furthermore, the presence of the two lateral microphone capsules adds, to sounds collected through the lateral microphone capsules located in the auricle and above defined, a full and direct perception of the sounds coming laterally. This way it is possible to perceive recorded sounds that move in up to down direction.
In an exemplary embodiment of the invention, two frontal microphone capsules are mounted to said dummy head, having a sound collection face oriented towards a frontal face of said dummy head, in particular said two sound collection faces of said two lateral microphone capsules, mounted to the auricles, are arranged at a predetermined first distance from each other and said frontal microphone capsules are arranged at a second distance from each other that is less than said first distance. In particular, the first distance is set between 15 and 13 cm and the second distance is set between 13 and 10 cm from the auricles, and, in particular, the helices of the two auricles are at a distance from each other set between 15 and 20 cm. In particular, the two frontal microphone capsules are arranged in a position h1 different in vertical direction from the lateral microphone capsules, and, in particular arranged from 1 to 3 cm higher or lower therefrom.
This way, with respect to the sounds collection obtained through the lateral microphone capsules above defined, it is obtained a sound collection coming from the frontal direction, simulating sonic sensations by the front part of the face of a person, and improving therefore the fidelity of sounds that come from a frontal direction.
Furthermore, while the lateral microphone capsules simulate the collection of sounds by the auricles of the human ear, the inner position of the frontal microphone capsules causes a sound collection carried out at an inner position. This effect is similar to the sound collection provided by the cochlea of the human ear, which is inner with respect to the auricles.
The auricles, and, in particular the helices of the two auricles, which in the human ear are the portions more lateral, are at a distance from each other set between 15 and 20 cm, in order to shield sounds coming from the top or from behind from sounds coming from the right and left sides.
In a possible exemplary embodiment, the two frontal microphone capsules are in a lower position in a vertical direction than the lateral microphone capsules.
The fact that the frontal microphone capsules are in a lower position than the lateral microphone capsules for a difference of height set between 1 and 3 cm, allows the listener to perceive in a more reliable way sounds moving in a vertical direction. In fact, the lateral microphone capsules perceive differently than the frontal one the intensity of sounds moving in up to down direction or vice versa. Such effect reproduces, like the human ear, the position of the cochlea which is lower than the auditory channel.
In a further exemplary embodiment of the invention, a partition wall is arranged between the two frontal microphone capsules. The partition wall is made of a material acoustically insulating, arranged to acoustically insulate the two frontal capsules.
This way, the presence of the partition wall provides an acoustic shield that makes it possible to each frontal capsule of distinguishing the sounds coming from the respective right and left sides.
According to another aspect of the invention, it is provided an audio product or an audio-visual product containing at least a part of audio recording obtained by a system of binaural recording as above defined.
According to a further aspect of the invention, it is provided a system for distributing multi-dimensional acoustic effects, comprising
This way, using the system of binaural recording, a plurality of audio tracks is obtained, each responsive to sounds originated in a predetermined position with respect to the system of binaural recording. In particular, each position of the space is referred to a body part identified using an object arranged to simulating the encumbrance of a human body.
In particular, the user that rests their head on the support, through the listening of the audio tracks played by the loudspeakers of the support, receives a listening experience which allows appreciation of multidimensional acoustic effects of the recorded sound source, corresponding to the selected body part.
This way, the system can be used as instrument of rehabilitation, for example to stimulate the hearing skills of autistic patients or hearing impaired persons. For example, a therapist can decide the activation of different body areas that have to be identified by the patient, or that in any case further stimulate the patient.
Further characteristic and/or advantages of the present invention will be made clearer with the following description of an exemplary embodiment thereof, exemplifying but not limitative, with reference to the attached drawings in which:
With reference to
A right loudspeaker 21 and a left loudspeaker 31 are mounted respectively to the right 20 and left 30 lateral support elements. The lateral support elements have respective sound emission faces 22, 32 that face towards a listening space 80. Rest element 10 provides a rest zone 13 for a portion 51 of the head.
A listening space 80 is defined between the two right 20 and left 30 support elements (as shown only in
A housing 13 is provided for a portion 51 of the head, configured to position the user's head with right and left ears 52, 53 oriented towards the right and left loudspeakers 21, 31. The right and left ears of the user create a listening axis 54, so that the axes of symmetry 60 of the tweeters 24, 34 are oriented with a predetermined angle of elevation a with respect to the listening axis 54 between a first elevation value substantially equal to zero and a second elevation value substantially equal to 45°. In the first case the tweeters 24, 34 have the respective axes of symmetry 60 aligned to each other and parallel to the listening axis, in the second case the tweeters 24, 34 have the axes of symmetry converging towards a point that is located higher than the listening axis 54.
With reference to
Tweeters 24 and 34 and woofers 23, 33 are arranged oriented in a predetermined direction at an angle in a horizontal plane by a predetermined inclination angle β set between 0° and 45°, preferably the inclination angle is set between 0° and 35°.
Furthermore, the tweeters 24, 34 have a respective center that is translated, along the longitudinal direction, proximally with respect to said user for a predetermined distance x set between 0 and 10 cm.

According to the invention, the auricles 106a, 106b are respectively configured to receive two lateral microphone capsules 105a, 105b so that they have a sound collection face 1015a, 1015b oriented laterally. The auricles 106a, 106b have a listening channel, not emulating the human ear, represented by a recess 1017a, 1017b defined between a helix 107a, 107b and a lobe 108a, 108b.
Each lateral microphone capsule 105a, 105b is located on the recess 1017a, 1017b with the sound collection face 1015a, 1015b that is inside the recess at the entrance 1018a, 1018b of the recess 1017a, 1017b.
This way, the sound is collected directly at the entrance 1018a, 1018b of the recess 1017a, 1017b that represents the listening channel and is located at the center of the auricle, and not after having crossed an artificial listening channel as the binaural microphone of the prior art of
The fact that the sound collection face 1015a, 1015b is located in the recess 1017a, 1017b allows auricles 106a, 106b and, in particular to the helixes 107a, 107b of the auricles, to perform an acoustic shielding and at the same time to collect for example sounds that come from behind or from above with respect to the head. This way, it is possible to discriminate better, like the human ear, sounds coming from a sound source positioned laterally, i.e. by the respective right or left sides, from sounds that come from behind or from the above.
The auricles, and in particular the helixes 107a, 107b of the two auricles 106a, 106b, that in the human ear are the more protruding portions, are preferably at a distance from each other set between 15 and 20 cm, in order to protrude more than the collecting faces 1015a and 1015b and to shield in part sounds that are from the above or from behind with respect to sounds that come from the right and left sides.
With reference to
This way, to the sound collection obtained through the lateral microphone capsules 105a, 105b defined above, also a sound collection coming from the frontal direction is added, simulating audio sensations from the front part of the face of a person, and improving therefore the fidelity with respect to sounds coming from a frontal direction.
The two frontal microphone capsules front 105c, 105d can have a linear distance d1 to each other less than the linear distance d2 between the two lateral microphone capsules (d1<d2). In particular, the distance d2 between the collecting faces 1015a and 1015b of the frontal microphone capsules 105a, 105b is set between 15 and 13 cm, and the distance d1 between the frontal microphone capsules 105c, 105d is set between 13 and 10 cm.
This way, whereas the lateral microphone capsules 105a, 105b simulate the listening collection by the auricles of the human ear, the inner position of the frontal microphone capsules 105c, 105d causes a sound collection which emulates the cochlea of human ear, which is inner within respect the auricles.
In a possible exemplary embodiment, the two frontal microphone capsules 105c, 105d are located at a difference in height 0<h<h1 from the two lateral microphone capsules, in a lower position in a vertical direction with respect to the lateral microphone capsules, as shown in
The difference of position in height of the frontal microphone capsules front 105c, 105d with respect to the lateral microphone capsules 105a, 105b aids to reproduce in a more realistic way the effect on the listener of sounds in movement in a vertical direction. In fact, the lateral microphone capsules 105a, 105b would collect in a different way from the frontal capsules 105c, 105d the intensity of sounds moving up to down or vice-versa. In particular, the frontal microphone capsules are lower or higher than the lateral microphone capsules for a difference in height set between 1 and 3 cm. This emulates the different position in height, in the human ear, of the cochlea with respect to the auditory channel. The lateral microphone capsules 105a, 105b can be configured for recording at a predetermined first intensity, and the frontal microphone capsules 105c, 105d can be configured for recording at a predetermined second intensity that is less than the first intensity for a difference in gain in dB set between 1 and 20 db. This way, a reduction of vestibular sensation is emulated, like in human ear, for sounds moving from a frontal direction that cross the skeletal parts of the face, with respect to sounds heard directly through the eardrum.
Furthermore, the two frontal microphone capsules 105c, 105d can be configured for recording at an opposite phase from the lateral microphone capsules 105a, 105b. Alternatively, the two frontal microphone capsules 105c, 105d can be configured for recording with respect to the lateral microphone capsules 105a, 105b with a phase shift of 20/40 samples.
With reference to
With reference to
The frontal microphone capsule 105e can be in a lower position in a vertical direction (d3<h) with respect to the other two frontal microphone capsules 105c, 105d, for improving the fidelity of recorded sound with respect to sounds that move in a vertical direction. This way, it is possible to discriminate better the directionality of the sound source moving up to down or vice-versa.
The two frontal microphone capsules 105c, 105d can be set for recording at a predetermined second intensity less than the first intensity of the lateral microphone capsules 105a, 105b for a difference in gain in decibel set between 5-8 dB, and the frontal microphone capsule 105e is configured for recording at a predetermined third intensity less than the first intensity for a difference in gain in decibel set between 3-5 dB. This way, a reduction of vestibular sensation is reproduced, like the human ear, for sounds moving from a frontal direction that cross the upper skeletal parts of the user's face, with respect to sounds moving from a frontal direction that cross the lower skeletal parts of the user's face.
The frontal microphone capsule 105e can be a cardioid capsule. In particular, a filter can be provided that cuts predetermined frequencies with respect to a full range of 1 hz-20 KHz. The filter can cut frequencies under 4-5 KHz and enhance frequencies between 12/20 KHz with a gain of 12 dB. This way, the behavior of the human ear for the sounds moving from a frontal direction that cross the skeletal parts of the face is reproduced. In particular, these sounds are reduced at lower frequencies and enhanced at higher frequencies.
Advantageously, at least one frontal microphone capsules 105c, 105d, 105e, is configured for oscillating a collected signal by an auto-panpot setting. This way, the ear of the listener will be stimulated for sounds coming from a frontal direction. The range of the auto-panpot can be set between a left/center point and a right/center point comprised between 20/30%, and the time for a movement between the left/center point and right/center point is comprised within 20/80 ms.
With reference to
The two further lateral microphone capsules 109c, 109d, which do not have an auricle, add a sound collection to that obtained through the lateral microphone capsules 105a, 105b located in the auricle 106a, 106b and above described, obtaining a better distinction between sounds coming frontally and sounds coming laterally.

As shown in
The element 109 has a tubular shape and is placed into the body of the soundproofing material, and preferably it is not in contact with the tubular element 11 used to support the lateral microphone capsules 105a-105e of the auricles. This way noise affecting the sound recording can be reduced.

In the example described in
Being the system of binaural recording 101 capable of keeping the information relative to the direction of the sound sources, the high fidelity audio tracks thus generated can be played with a reproduction system of the same fidelity level like the one above described with reference to the
With reference to
Such audio tracks, used in combination with a mobile device 980 and a head support for audio reproduction, allow the patient to listen sounds that are perceived as coming from the position mn in which the sound source has been activated during recording. Combining more audio tracks it is possible to reproduce sounds that move with respect to the patient, in a predetermined way according to the cells mn chosen for reproduction. For example, it can be produced audio tracks that make the patient perceive sounds that move up to down or vice-versa.
It is also possible to record audio tracks relative to moving sound sources, which cross more zones mn. In this case such audio tracks that cover more zone can be played choosing the relative positions for reproduction, as hereinafter described.
With reference to
If the interface 1000 is either a tablet or a smartphone, it can be equipped with touch screen 1000′ where it is given an image 1002 depicting a body and a plurality of areas overlapped to body parts. In particular, the user, for example a patient that is located on the support of audio reproduction, or a therapist that wishes the patient to perceive some chosen sounds, interacting with the image 1002, controls reproduction of audio tracks recorded with the criteria above described. Such controls can be performed both by a selection of the areas present in the image 1002, near body parts, and by a selection of a stimulation path which runs through a predetermined succession of areas of the image 1002. A database 1003 can contain both audio tracks of recordings relative to predetermined body parts 1004, and audio tracks relative to paths 1005 that cross multiple body parts. A control unit 1006, present in the software, is adapted to control the head support in order to reproduce the audio tracks obtained by the system of binaural recording. The audio tracks activated are sent to the head support for audio reproduction by wireless connection or by cable connection by means of a player 1007. For example, it can be played a sound perceived at the height of the right foot of the patient, or a sound that moves from the right edge of the foot to the head, and the like.
