This invention relates to improved microphone attachment for use in conjunction with microphones. Specifically, the microphone attachment is designed to facilitate to reduce background noise and relates to mitigating unwanted noise picked up by a microphone, for example, when recording a performance or recording messages.
The increasing sophistication of music recording devices has made home recording prevalent among musicians. Complex and technologically advanced equipment has become more affordable and thus, more accessible to professional and non-professional musicians. However, a musical recording can only be as good as the recording environment permits. This environment includes the placement and stability of the equipment, as well as the comfort of the surroundings.
A microphone is the key element in a recording environment. It is critical that it be positioned in front of the performer’s mouth or instrument to optimize the microphone’s available frequency range. In the environment of use of a microphone, there is often substantial physical activity of the performer. The vibrations from such movements, or of the sounds themselves, may cause a distorted sound or background voices.
Currently available microphone attachments used to record performance in an unprocessed space for sound recording, a sound not related to the performance can be picked up by the microphone. Ambient noise or “room tone” may include noise that occurs in space, such as the sound of an air conditioner or computer fan in a room. Noises that enter the space from the outside, such as traffic noise, can also contribute to the ambient noise level. The ambient noise picked up by the microphone during recording of the performance may impair the quality of the recording.
Because of these issues, performance is often recorded in a room that is specifically processed for sound recording. For example, the interior surfaces of the room may be treated with sound absorbing materials to reduce the reflection of the performance sound in the room. The windows and doors of the room may be constructed or reinforced with materials designed to reduce the penetration of external noise into the space. Additional measures may be taken to reduce machine noise in the room. These measures can make processing a room for sound recording a costly and complex attempt. In addition, when the sound recording occurs in the house, it may not be desirable to change the appearance of the room as needed to accommodate the sound recording.
By looking at prior art multiple types of advancements have been seen in similar regards. For instance, a Noise mitigating microphone attachment bearing U.S. Pat. 9,118,989 is issued to Kaotica Ip Corp. The patent relates to methods, systems and apparatus are described for mitigating noise during sound recording. A noise mitigating microphone attachment comprises a foam structure. A first cavity extending from a first opening at a surface of the foam structure and into the foam structure. A microphone is inserted into the first cavity with sound receiving elements of the microphone fully installed in the structure. A second cavity extending from a second opening at the surface of the foam structure and into the foam structure is configured to receive sound from a sound source. The first cavity is fluidly connected to the second cavity within the foam structure so that a junction is formed between the first cavity and the second cavity. The junction, the sound cavity, and the sealing of the microphone work to shield the sound receiving elements of the microphone from sound other than received through the second opening.
Another patent on Electroacoustic devices with noise-reducing capability bearing U.S. Pat. 7,466,838 is issued to William T. Moseley. The patent relates to new and improved electroacoustic devices each including at least one transducer assembly having one or more microphones typically mounted on a baffle plate and disposed in substantially the same acoustic plane as a speaker or speakers. In the various embodiments, at least one microphone and at least one speaker face the same or opposite directions. Each microphone may be parallel to or oriented at an angle with respect to the speaker. In other embodiments, the speaker includes a central opening or cavity in which a microphone having one of various orientations is provided. The orientations of the microphone or microphones with respect to the speaker or speakers minimize adverse noise reduction effects associated with the differences in sensitivities, frequency responses and phase responses and acoustic time delays between the microphones and the speaker or speakers, as well as minimize sound reflections that are picked up by the microphone or microphones.
A Noise cancellation system with lower rate emulation bearing U.S. Pat. 10,431,198 is issued to Cirrus Logic Inc. The patent relates to a noise cancellation system, comprising: an input for a digital signal, the digital signal having a first sample rate; a digital filter, connected to the input to receive the digital signal; a decimator, connected to the input to receive the digital signal and to generate a decimated signal at a second sample rate lower than the first sample rate; and a processor. The processor comprises: an emulation of the digital filter, connected to receive the decimated signal and to generate an emulated filter output; and a control circuit, for generating a control signal on the basis of the emulated filter output. The control signal is applied to the digital filter to control a filter characteristic thereof.
Another U.S. Pat. 5,699,436 for a Hands free noise canceling headset is issued to noise Cancellation Technologies Inc. The patent relates to the area of active noise cancellation headsets, the noisy environment often encountered in the link with communication systems causes lack of intelligibility on the outward communications path. Consequently, another in-wire cancellation channel to enhance the intelligibility is required. This additional processing channel adds to the cost of the headset. The invention uses residual microphones (12) to reproduce the sound that remains in the ear after cancellation so that the controller (13) can make further adjustments through filter (15) and LMS adapter (14) to the anti-noise signal.

The present invention is directed to a microphone Noise Abatement Attachment aimed to provide noise free recordings.
Embodiments of the present invention relate to mitigating noise during a capture of sound recording with a noise mitigating microphone attachment. Noise can refer to any unwanted sound, i.e., sound that is not desirable to have a microphone detect during a recording. For example, it may be desirable that noise such as ambient noise and reflections of sound waves originating from a performance sound source is mitigated. The noise mitigating microphone attachment can reduce the amount of noise that a microphone will pick up during a sound recording.
The assembly 101 is comprised of a material such as foam which is curved in shape from outside with an inner hollow end 102 along with opening 103. The inner hollow 102 and opening 103 are square shaped and allow microphone 605 to be placed into cavity 104 in the bottom of the assembly 101 which reduces the background noise while recording. A pop filter 506 may be attached to opening 103 to further reduce unwanted noise.
In some embodiments, a microphone coupled to a mobile device is used with the noise mitigating microphone attachment. Where the term “microphone” is used herein, a mobile device or other device having a microphone attachment may be used. For example, a mobile device can extend through the microphone cavity such that a microphone connected to the mobile device extends into the sound cavity.
The portable assembly as per its further embodiments is developed from high quality material which aims to maintain its effectiveness over longer period of time.
The embodiments described herein provide a portable device that can be produced at low-cost relative to the cost of existing solutions for noise Abatement in recording environments. The noise Abatement microphone attachment can be used for sound recording in a home studio, outdoors, or other environment to protect a microphone from picking up unwanted sounds during a performance. A microphone 605 can be inserted into a first opening 107 of the Abatement microphone attachment and extend through a microphone cavity 104 into a sound cavity 102. The sound cavity 102 can extend from a second opening 103 at the surface of the noise mitigating microphone attachment. A performance sound source is typically located proximate to the second opening 103. Sound incident on the exterior of the noise mitigating microphone attachment is attenuated by the structure of the noise Abatement microphone attachment.
