Provided a robot for assisting hearing of a user, while minimizing an influence on the surroundings. The robot includes a speaker, a microphone configured to recognize a voice, a processor configured to acquire a position of a user's face when a hearing aid command is acquired on the basis of the voice recognized through the microphone, and a driving unit configured to cause the speaker to be moved toward the position of the user's face, wherein the processor acquires a sound which is a target of hearing aid, generates an assistant sound by amplifying a predetermined frequency band of the sound or converting the predetermined frequency band of the sound into a different frequency band, and outputs the assistant sound through the speaker.

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.

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 an ear worn device (1), particularly a wireless headphone or a hearing aid, comprising a first module (10) configured to be inserted at least partially into an ear canal (2a) of a user, wherein the first module (10) comprises a loudspeaker (11) configured to emit sound into the ear canal (2a) of the user, and wherein the first module (10) comprises at least one microphone (12, 13) configured to pick up sound, and a second module (20) configured to be arranged outside of the concha cava (2b) adjacent to said ear canal (2a) of the user when the first module (10) is inserted into said ear canal (2a), wherein the second module (20) comprises at least one electronic component (21) which is operatively coupled to the loudspeaker (11) and/or the at least one microphone (12, 13) of the first module, wherein the first ambient microphone (12) is configured to be arranged behind the tragus (2c) of the ear (2) of the user adjacent to the ear canal (2a) and faces away from the ear canal (2a).

A hearing aid, in particular a BTE hearing aid, includes a base part and an ear hook which can be attached to the base part. In an assembled state, the base part and the ear hook are connected by a nozzle and a receptacle. A sound channel runs through the nozzle. The nozzle has a circumferential outer wall and the receptacle has a circumferential inner wall. In the assembled state, a circumferential sealing ring having a thickness is disposed between the outer wall and the inner wall. The sealing ring lies in particular in an annular groove and the inner wall preferably has two reduction sections which compress the sealing ring.

A speech intelligibility enhancing system for difficult acoustical conditions is disclosed, the speech intelligibility enhancing system comprising at least one ear plug (201) for insertion in an ear canal (218) of a person, the at least one ear plug being arranged with an ear canal facing portion (401) and an environment facing portion (402), and the at least one ear plug comprising an acoustically attenuating path (214; 214, 213) comprising a vent (214) coupling said environment facing portion (402) with said ear canal facing portion (401); and an electroacoustic path (202, 204, 209; 202, 203, 204, 208, 209, 210, 211, 212) comprising a microphone (202) at said environment facing portion (402), a variable gain (204) and a loudspeaker (209) at said ear canal facing portion (401); wherein said acoustically attenuating path (214; 214, 213) is arranged with a transfer function from said environment facing portion (402) to said ear canal facing portion (401) having a low pass characteristic having a low pass cut¬off frequency and said low pass characteristic attenuating sound by a nominal attenuation (Go) for frequencies below said cut-off frequency.

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.

A system for stimulation of a patient's ipsilateral cochlea, having at least two spaced apart patient-worn microphones for providing first and second audio signals from ambient sound; a sound processor for generating an ipsilateral auditory nerve stimulation signal in a plurality of output channels from at least one of the input audio signals; and a stimulation assembly for being implanted within the ipsilateral cochlea and having a plurality of stimulation channels for ipsilateral stimulation of the patient's hearing according to the ipsilateral auditory nerve stimulation signal. The sound processor comprising a DOA unit for determining periodically a main direction of incidence of ambient sound from a sound source by analyzing the first and second audio signals, and a directional information coding unit for coding information concerning the determined main direction of incidence in the ipsilateral auditory nerve stimulation signal in manner to enable the patient to localize the sound source.

A hearing aid assembly comprising a receiver comprising a front chamber and a back chamber being acoustically coupled to respective front and back chamber openings, and acoustical guiding means for guiding air from at least one of the front and back chamber openings to an air mixing zone for mixing air from the front and back chamber openings.

The hearing device further comprises a control unit operatively connected to said memory and to said signal processing unit, and configured to compare said current estimate of the acoustic feedback path with said reference estimate of the acoustic feedback path, and to provide a current feedback path difference measure, and to determine a current estimate of real ear to coupler difference from the current feedback path difference measure. This has the advantage facilitating the mounting of the ear ITE-part. The invention may e.g. be used in hearing aids for compensating a user's hearing impairment.
