  • Patent number: 11064301
    Abstract: 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.

  • Patent number: 10951993
    Abstract: With regards to a hearing assistive device, a user's speech can be 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. Furthermore, the when the hearing assistive device experiences feedback, the amplification of the feedback can cause damage to the user's hearing. Therefore, mitigating the acoustic feedback effect of assistive hearing devices can generate a more efficient and comfortable hearing device. The acoustic feedback can be mitigated by leveraging a dynamic range controller and a howling detector which comprises a user interface and a status indicator.

  • Patent number: 10602275
    Abstract: 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.
