The present subject matter relates generally to hearing assistance devices, and in particular to user adjustments to a tinnitus therapy generator within a hearing assistance device.
Modern hearing assistance devices, such as hearing aids, typically include digital electronics to enhance the wearer's listening experience. Hearing aids are electronic instruments worn in or around the ear that compensate for hearing losses by specially amplifying sound. Hearing aids use transducer and electro-mechanical components which are connected via wires to the hearing aid circuitry.
Tinnitus is a condition in which a patient perceives sound in their ear in the absence of corresponding external sound. While ringing of the ears is associated with tinnitus, other types of sounds can be perceived and can be sporadic, intermittent or continuous. Tinnitus can be caused by a number of conditions or injuries, but regardless of cause can be debilitating and decrease a patient's quality of life.
What is needed in the art is an improved system for generating tinnitus therapy.
Disclosed herein, among other things, are methods and apparatus for user adjustments to a tinnitus therapy generator within a hearing assistance device.
One aspect of the present subject matter relates to a method of providing therapy for tinnitus to a patient. A user interface is provided for patient input to adjust settings of a tinnitus therapy generator. Sound is transmitted from the tinnitus therapy generator to the patient via a hearing assistance device receiver to provide therapy for tinnitus. In various embodiments, settings adjustable by the patient include but are not limited to output levels and frequency response.
One aspect of the present subject matter relates to system including a hearing assistance device for providing therapy for tinnitus to a patient. The system includes a tinnitus therapy generator configured to transmit sound to the patient via a hearing assistance device receiver to provide therapy for tinnitus. Various embodiments of the system include a user interface for patient input to adjust settings of the tinnitus therapy generator, the user interface in communication with the hearing assistance device. In various embodiments, settings adjustable by the patient include but are not limited to output levels and frequency response. Other aspects are provided without departing from the scope of the present subject matter.
This Summary is an overview of some of the teachings of the present application and not intended to be an exclusive or exhaustive treatment of the present subject matter. Further details about the present subject matter are found in the detailed description and appended claims. The scope of the present invention is defined by the appended claims and their legal equivalents.
The following detailed description of the present subject matter refers to subject matter in the accompanying drawings which show, by way of illustration, specific aspects and embodiments in which the present subject matter may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the present subject matter. References to “an”, “one”, or “various” embodiments in this disclosure are not necessarily to the same embodiment, and such references contemplate more than one embodiment. The following detailed description is demonstrative and not to be taken in a limiting sense. The scope of the present subject matter is defined by the appended claims, along with the full scope of legal equivalents to which such claims are entitled.
The present subject matter relates generally to hearing assistance devices, and in particular to user adjustments to a tinnitus therapy generator within a hearing assistance device. The hearing assistance devices referred to herein include, but are not limited to hearing aids. One aspect of the present subject matter relates to a method of providing therapy for tinnitus to a patient. A user interface is provided for patient input to adjust settings of a tinnitus therapy generator. Sound is transmitted from the tinnitus therapy generator to the patient via a hearing assistance device receiver to provide therapy for tinnitus. The patient input is received from the user interface and used to adjust output level and frequency response of the sound transmitted by the hearing assistance device receiver to adjust the therapy for the tinnitus. Other settings of the tinnitus therapy can be adjusted without departing from the scope of the present subject matter
Some hearing assistance devices include an interface for patients to adjust the gain and compression settings of their hearing aids. The present subject matter provides for patient adjustment of tinnitus therapy stimulus so that patients can program the spectrum of the tinnitus therapy stimulus, allowing for the selection of individually optimized settings. The subjective nature of tinnitus often makes it difficult for the professional to understand the patient's percept, and thus program sound therapy devices for the patient. There is no universally accepted prescription for sound therapy as patient variability prevents one treatment philosophy from being successful with all tinnitus patients. One advantage of the present subject matter is that the patient becomes an active participant in his or her treatment and can provide direct input in the programming of the tinnitus therapy stimulus, rather than indirect input to the professional, who then programs a sound therapy device for the patient.
Some previous devices provide a means by which the patient can adjust the volume of the tinnitus therapy sound. However the initial programming of the starting level and frequency response of the tinnitus therapy device is left up to the professional. These previous devices allow for only gross adjustment of level, restricting the patient's involvement in the selection and optimization of the tinnitus therapy stimulus. The present subject matter for the tinnitus therapy stimulus allows the patient to manually adjust the level and frequency response of the tinnitus sound generator via an intuitive, interactive user interface. Other settings of the tinnitus generator can be adjusted by the patient without departing from the scope of the present subject matter.
This present subject matter allows the tinnitus patient to provide direct input to the programming of the tinnitus therapy device. The patient is able to explore a variety of settings and choose the settings that are most comfortable, relaxing, and desirable, resulting in a treatment that is highly individualized. In various embodiments, the patient interface includes a computer. In one example, the computer has a keyboard and mouse interface. In another example, the computer has a touch screen instead of or in addition to the keyboard and mouse. Other interfaces, such as handheld devices and laptop devices, voice recognition, gesture sensing, etc. can be used without departing from the scope of the present subject matter. In various embodiments, existing hearing assistance device interfaces or fitting software can be used by the patient to adjust settings of the tinnitus therapy generator. One advantage of using these interfaces to adjust the tinnitus therapy stimulus is that it allows the patient to play an active role in the treatment of his/her tinnitus by exploring various settings for the tinnitus therapy stimulus and selecting the settings that are most appropriate for him/her.
Upon launching software for the tinnitus therapy stimulus, the patient begins with settings for the tinnitus therapy stimulus that are programmed to the device by the professional, in an embodiment. The layout of the space is generated specifically for those settings. Once that unique layout is generated, the patient is able to explore a variety of settings for the tinnitus therapy stimulus by moving a cursor through the space. These movements systematically adjust the output levels of the tinnitus therapy stimulus in 16 bands, independent of the amplification prescribed for treatment of hearing loss. As the patient moves the cursor, the settings for the tinnitus therapy stimulus update in real-time, allowing the patient to evaluate the sound quality of the therapy stimulus in an embodiment. The patient has the option of listening to any of the settings and easily comparing multiple settings. Once a favorite setting for the tinnitus therapy stimulus is determined, those parameters are stored to the programming software and the hearing aid, in various embodiments. Similar functionality could be achieved with an alternate user interface. For instance, the patient could manipulate the settings of the tinnitus therapy stimulus using an equalizer-like user interface. This present subject matter involves the patient in the fitting process and removes guesswork for the professional.
It is understood that variations in communications standards, protocols, and combinations of components may be employed without departing from the scope of the present subject matter. Hearing assistance devices typically include an enclosure or housing, a microphone, hearing assistance device electronics including processing electronics, and a speaker or receiver. Processing electronics include a controller or processor, such as a digital signal processor (DSP), in various embodiments. Other types of processors may be used without departing from the scope of this disclosure. It is understood that in various embodiments the microphone is optional. It is understood that in various embodiments the receiver is optional. Thus, the examples set forth herein are intended to be demonstrative and not a limiting or exhaustive depiction of variations.
The present subject matter can be used for a variety of hearing assistance devices, including but not limited to, cochlear implant type hearing devices, hearing aids, such as behind-the-ear (BTE), in-the-ear (ITE), in-the-canal (ITC), or completely-in-the-canal (CIC) type hearing aids. It is understood that behind-the-ear type hearing aids may include devices that reside substantially behind the ear or over the ear. Such devices may include hearing aids with receivers associated with the electronics portion of the behind-the-ear device, or hearing aids of the type having receivers in the ear canal of the user. Such devices are also known as receiver-in-the-canal (RIC) or receiver-in-the-ear (RITE) hearing instruments. It is understood that other hearing assistance devices not expressly stated herein may fall within the scope of the present subject matter.
This application is intended to cover adaptations or variations of the present subject matter. It is to be understood that the above description is intended to be illustrative, and not restrictive. The scope of the present subject matter should be determined with reference to the appended claims, along with the full scope of legal equivalents to which such claims are entitled.
The present application claims the benefit under 35 U.S.C. § 119(e) of U.S. Provisional Patent Application 61/659,794, filed Jun. 14, 2012, the disclosure of which is hereby incorporated by reference herein in its entirety.
