An earpiece includes: a first end; a second end opposite from the first end; a first channel extending from a first location that is closer to the first end than to the second end, to a second location that is closer to the second end than to the first end; and a first diaphragm, wherein the first diaphragm has a first surface and a second surface opposite the first surface, the first surface of the diaphragm configured to be in fluid communication with a lumen in the first channel, wherein the first diaphragm extends in a direction that is parallel to, or that forms an acute angle with, a longitudinal axis of the first channel.

A hearing aid system for selective modification of background noises may include at least one processor. The processor may be programmed to receive a plurality of images from an environment of a user captured by a wearable camera during a time period and receive an audio signal representative of sounds acquired by a wearable microphone during the time period. The processor may determine that at least one of the sounds was generated by a sound-emanating object in the environment of the user, but outside of a field of view of the wearable camera and retrieve from a database information associated with the sound-emanating object. Based on the retrieved information, the processor may cause selective conditioning of audio signals acquired by the wearable microphone during the time period and cause transmission of the conditioned audio signals to a hearing interface device configured to provide sounds to an ear of the user.

A system for selectively amplifying audio signals may include a microphone configured to capture sounds from an environment of a user. The system may also include a processor programmed to: receive audio signals representative of the sounds captured by the microphone; cause selective conditioning of at least one audio signal received by the microphone from a region associated with the recognized individual; and cause transmission of the at least one conditioned audio signal to a hearing interface device configured to provide sound to an ear of the user.

A system may include a wearable camera configured to capture images and a microphone configured to capture sounds. The system may also include a processor programmed to receive the images; identify a representation of one or more individuals in the images; receive from the microphone a first audio signal associated with a voice; determine, based on analysis of the images, that the first audio signal is not associated with a voice of any of the one or more individuals; receive from the microphone a second audio signal associated with a voice; determine, based on analysis of the images, that the second audio signal is associated with a voice of one of the one or more individuals; and cause a first amplification of the first audio signal and a second amplification of the second audio signal. The first amplification may differ from the second amplification in one aspect.

Various implementations include systems for processing audio signals. In particular implementations, a process includes receiving an audio signal, wherein the audio signal includes a speech component of the user and a noise component; filtering the audio signal with a self-speech filter that utilizes an intrinsic user vector to filter out the speech component, wherein the intrinsic user vector is determined based on a voice input of the user; and outputting a filtered audio signal in which the speech component of the user has been substantially removed from the audio signal.

An in-ear electronic device comprising: an enclosure having an enclosure wall that defines an interior chamber surrounding a transducer and an opening from the interior chamber to an ambient environment surrounding the enclosure; and an acoustic valve comprising a driven member coupled to a driving member having a lever and a shape memory alloy operable to cause the driven member to open and close the opening upon application of a current.

A system may include a wearable camera configured to capture a plurality of images from an environment of a user and a microphone configured to capture sounds from an environment of the user. The system may also include a processor programmed to receive the images; identify a representation of an individual in one of the images; identify a lip movement associated with a mouth of the individual, based on analysis of the images; receive audio signals representative of the sounds; identify, based on analysis of the sounds, an audio signal associated with a voice of the individual; and cause transmission of the audio signal to a hearing interface device configured to provide sound to an ear of the user.

A method operates a hearing aid system in which a dynamic range scheme for an automatic gain control is modified depending on the situation. A gain factor is set by the automatic gain control which has a dynamic range processor operated with a dynamic range scheme defining the gain factor in dependence on a level of an input signal. A corresponding hearing aid system carries out this method.
