20220167099 · 2022-05-26 · ·

A method of providing an alert for a user by a hearing device configured to be worn at an ear of the user includes providing user-related data including information about at least one of the user, an ambient environment of the user, or a property of the hearing device worn by the user; characterized by providing vehicle-related data associated with at least one vehicle in a vicinity of the user, the vehicle-related data including information about a property of the vehicle; determining, based on the user-related data and the vehicle-related data, a relevance measure indicative of a probability that the user is endangered by the vehicle; and controlling an operation of the hearing device depending on the relevance measure, the operation alerting the user about the vehicle.

EARPIECES

An earpiece includes an electro-acoustic transducer and a housing that supports the electro-acoustic transducer such that the housing and the electro-acoustic transducer together define a first acoustic volume and a second acoustic volume. The electro-acoustic transducer is arranged such that a first radiating surface of the transducer radiates acoustic energy into the first acoustic volume and a second radiating surface of the transducer radiates acoustic energy into the second acoustic volume. A mesh is disposed along an outlet of the housing and is arranged to inhibit debris from entering the front acoustic volume. A first microphone is supported in the housing. The first microphone includes a microphone port for sensing pressure. A chimney surrounds the microphone port and mechanically couples the first microphone to the mesh.

In one embodiment, a MEMS microphone can be coupled to an acoustic horn to provide various benefits and improvements including, but not limited to, at-a-distance acoustic signal reception with improvements in signal-to-noise ratio and directional preference.

DAMPING FILTER FOR A HEARING DEVICE

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.

Implantable microphone management
11722815 · 2023-08-08 · ·

A device, including an implantable microphone, including a transducer, and a chamber in which a gas is located such that vibrations originating external to the microphone based on sound are effectively transmitted therethrough, wherein the transducer is in effective vibration communication with the gas, wherein the transducer is configured to convert the vibrations traveling via the gas to an electrical signal, the chamber and the transducer correspond to a microphone system, wherein the chamber corresponds to a front volume of the microphone system, and the transducer includes a back volume corresponding to the back volume of the microphone system, and the implantable microphone is configured to enable pressure adjustment of the front and/or back volume in real time.

Ultrasonic hearing system and related methods

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.
