A system for detecting feedforward instability in a wearable audio device. The audio device includes an electro-acoustic transducer that is configured to develop sound for a user, a housing that holds the transducer, a feedforward microphone that is configured to detect sound outside of the housing and output a microphone signal, and an opening in the housing that emits sound pressure from the transducer that can reach the microphone. A feedforward instability detector is configured to apply two filters to the microphone signal. A first filter passes more energy in a frequency band than does a second filter, to develop a filtered signal. The filtered signal is compared to the microphone signal outside of the frequency band, to develop a comparison signal that is indicative of feedforward instability in the frequency band.

A hearing aid and related systems and methods are disclosed. In one implementation, a hearing aid system may include a wearable camera; a microphone; and a processor. The processor may be programmed to receive images captured by the camera; receive audio signals representative of sounds received by the at least one microphone; determine a look direction of the user based on analysis of the images; determine an amplitude of a first audio signal associated with an individual or object in a region associated with the look direction of the user; determine an amplitude of a second audio signal from a region other than the look direction of the user; adjust the second amplitude in accordance with the first amplitude; and cause transmission of the second audio signal at the adjusted amplitude to a hearing interface device configured to provide sound to an ear of the user.

The present disclosure relates to a hearing device having a microphone, where most of the microphone is shielded by an outer shielding of the hearing device. An inlet in the outer shielding allows sound from outside the hearing aid to travel to the microphone to be picked up by it. However, the combination of the microphone and the inlet results in the microphone becoming more sensitive at some audible frequencies. A damping filter positioned in connection with the inlet acts to counter the acoustic effect of the inlet by damping sound in the audible frequency range, where the microphone has increased sensitivity.

The invention relates to a communication system comprising a hearing aid, a communication unit, a relay server, a rule processing server, and at least one external device, wherein the rule processing server comprises a data communication interface to communicate with said relay server and with a plurality of external devices over a plurality of data communication channels, a rule processor, and a rule base comprising a set of rules, each rule defining an action to be triggered in response to a trigger event. Said rule processor is configured to generate an action request signal in response to an event signal representing a trigger event. Said action request signal is configured to cause an action of at least one of the hearing aid, the communication unit, the relay server or the external device, and wherein said action request signal carries information that designates at least one of said devices and at least one action to be performed of said at least one device. Said communication system further comprises an event detector that is configured to detect a trigger event and to generate the event signal in response to a detection of the trigger event.

A hearing system to activate an auditory system using cerebrospinal fluids includes at least one processor configured to receive an audio signal captured using a sound sensor (e.g., a microphone), extract temporal and spectral features from the audio signal, and create modulated ultrasound signals in a range of 20 Hz to 20 kHz with ultrasound carrier frequencies in the range of 50 kHz to 4 MHz, which are ultrasound frequencies that are well-suited to reach the cerebrospinal fluids (e.g., can pass across the skull/bones to reach the cerebrospinal fluids). The system further includes at least one ultrasonic transducer which receives the modulated signal and delivers the modulated signal to the body and activates the auditory system via vibration of cerebrospinal fluids that vibrate cochlear fluids, bypassing the normal conductive pathway that uses middle ear bones and minimizing bone conduction and distortion through the skull.

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.
