Various implementations include hearing assist devices and systems for processing audio signals. In particular implementations, a process includes receiving an input signal via a microphone; performing a sound pressure level (SPL) shift that decreases a gain of the input signal to generate a gain reduced audio signal; amplifying the gain reduced audio signal using dynamic range compression to generate an amplified audio signal; generating a noise reduced amplified signal using active noise reduction that simultaneously processes the input signal; and outputting the noise reduced amplified signal to an electrodynamic transducer.

Provided is a method of mounting at least one hearing device component (14) inside a hearing device shell (12). Said method comprises the steps of threading a fixture means (16) through a hole (18) formed in the wall of the hearing device shell (12) and attaching the hearing device component (14) to the end of the portion of the fixture means (16) protruding into the inside of the hearing device shell (12). The method further comprises manipulating the portion of the fixture means (16) protruding to the outside of the hearing device shell (12) such to position the hearing device component (14) in a predetermined position, and fixing the positioned hearing device component (14) to the inner wall of the hearing device shell (12).

A hearing device, particularly a hearing aid, has a housing, a signal processing unit arranged in the housing, a first sound generator disposed in the housing, and a second sound generator. The first sound generator and the second sound generator are configured to convert an output signal from the signal processing unit into sound. The second sound generator is a thermo-acoustic transducer.

Hearing devices configured to fit within the bony portion of the ear canal and batteries that may be used with same.

The invention regards a communication device which is adapted for placement in a users ear. The communication device comprises a shell part enclosing an input transducer for receiving an input signal, a signal processing device and an output N transducer for providing a signal perceivable as sound, a battery located at a surface part of the shell which is facing away from the head of the user, a transmission and reception circuit for transmission and/or reception of electromagnetic energy. According to the invention an antenna for radiating and/or receiving electromagnetic energy is provided such that it has a first surface turned towards the surroundings and a second surface located in close proximity of the battery.

The subject matter described herein provides systems and techniques for controlling the production of eNoise in an audio playback system. The eNoise may be an audible noise produced when a current, such as a noise/ripple current, flows through a battery of the audio playback system. Such eNoise may be reduced by limiting the current, such as noise/ripple current, flowing through the battery. In some examples, the noise/ripple current may be diverted to the main board of the audio playback system by adding a source of current. A circuit to produce such a current may include transistor(s), capacitor(s), and/or resistor(s). Using the current source and/or such a circuit may also divert the noise/ripple current away from the battery, thereby reducing the eNoise produced.

In a binaural hearing aid system audio signals are transmitted between an antenna facility of a left ITE hearing aid and an antenna facility of a right ITE hearing aid. Binaural beam forming is based on a natural directivity of the pinna and/or based on a head shadowing effect. Each antenna facility has an antenna arrangement with a coil core made of magnetically permeable material, and extending along a longitudinal axis, a further electric hearing aid component, which emits electromagnetic interference radiation, and an at least partially planar shield made of magnetically permeable material. The shield is arranged between the antenna arrangement and the further hearing aid component transversely to the longitudinal axis of the coil core and the shield is arranged at a distance of 50 to 150 micrometers from the coil core, preferably 75 to 100 micrometers.

A sound generator including a housing having a first wall portion with a housing opening, a shielding element covering at least a portion of the first wall portion and having a shield opening, where the shielding element covers a portion of the first wall portion.

A head-worn device comprises a housing with an insulating housing wall and is housing a conducting element (24; 31) having at least one end embedded into the housing wall, and a component (22; 30) being arranged adjacent to the conducting element (24; 31). The component (22; 30) and the conducting element (24; 31) are being separated by a partitioning element (26; 28; 40) provided as an insulator. The partitioning element (26; 28; 40) is having a shape increasing the travelling distance for a spark between the conducting element (24; 31) and the component (22; 30) by at least 40%, and a thickness and a Dielectric Strength sufficient to resist 3 kV without breaking down.

Presented herein are techniques for time interleaving the sampling of input signals with the delivery of stimulation signals to a recipient of an implantable electrically-stimulating hearing prosthesis. The input signals, which are received via one or more input channels and sampled by a sound processing unit, are susceptible to electrical feedback from the stimulation signals. As such, in accordance with embodiments presented herein, the sampling of the input signals by the sound processing unit, and the delivery of the stimulation signals to the recipient, are synchronized with one another so as to avoid stimulation-evoked electrical feedback within the input signals.
