For many hearing assistive devices, the user's speech is received at a larger amplitude signal than the speech of someone speaking to the user. Since the user's speech is also picked up by the microphone and feed through the speaker causing an acoustic feedback effect, the user may have to constantly adjust the volume of the hearing assistive device to achieve a more comfortable volume based on where the speech is coming from. Therefore, mitigating the acoustic feedback effect of assistive hearing devices can generate a more efficient and comfortable hearing device.

User interface and method to discover hearing sensitivity of user on smart phone
Employing outputted tones on a client device and/or headset is facilitated to identify hearing sensitivity of a user for both ears at various frequency bands and provide an indication of the users hearing sensitivity as compared to a normal hearing curve of a plurality of users on the same client device and/or headset or differing client devices and/or headsets.
Systems and methods are presented for detecting a direction of an incoming projectile and determining a source location of the projectile. One or more resonant sensors (comprising a plate, piezo electric sensor, etc.) can be arranged, where shockwaves from the projectile (e.g., shockwaves from a bullet travelling at supersonic speeds) are incident upon the plate and cause the plate to resonate. The resonance causes an electrical signal to be generated by the piezo electric sensor (e.g., a piezo electric film sensor), the greater the degree of resonance in the plate, the higher the magnitude of signal generated by the piezo electric sensor. By comparing the magnitude of the piezo electric signals across the array of resonant sensors it is possible to determine a trajectory of the projectile and hence a location of the source of the projectile. Acoustic waves can also be generated by muzzle waves.

Audio enhancement via beamforming and multichannel filtering of an input audio signal
Enhancing audio content based on application of different gains to different frequency bands of an audio signal is disclosed. Audio information contained in an input signal can undergo beamforming to provide an initial adjustment to the audio information, e.g., noise reduction, etc. In an embodiment beamforming can comprise double-beamforming in which first audio information is adjusted based on second audio information and the second audio information is adjusted based on the first audio information. Different gains can be applied to content in determined frequency bands, resulting in an amplified signal. In some embodiments, the gains can be related to hearing sensitivity of a listener, e.g., via a hearing sensitivity model. The amplified audio information from each frequency band can then be recombined. The recombined signal can be level limited and subjected to further digital and analog gains. The resulting output, e.g., enhanced audio, can be individually adapted for a listener.
Disclosed is a graphical user interface operational on a portable device that allows users to test their minimum audio hearing level at various frequencies using a single button. The graphical user interface generates sound frequencies that are played to the user, one ear at a time. Starting from zero decibels, sound intensity levels are gradually increased to intensity levels perceptible by the user. The users indicate recognition of the sound frequency by interacting with the graphical user interface. The intensities of the sound pressure levels (SPLs) are registered as estimates of a user's hearing sensitivity at the tested frequency bands. The process is repeated at different frequency bands for each ear, and hearing levels for each ear established.
Described herein are apparatuses, systems and methods that facilitate user adjustment of an audio effect of an audio device to match the hearing sensitivity of the user. The user can tune the audio device with a minimum perceptible level unique to the user. The audio device can adjust the audio effect in accordance with the minimum perceptible level.
