Abstract: Disclosed is an annular ear cushion for an earphone configured to be worn at an ear of a user. The ear cushion is configured to abut the head of the user along an annular contact surface of the ear cushion and to abut or face a housing of the earphone along an annular attachment surface of the ear cushion when the user is wearing the earphone in its intended position, thereby reducing the level of sound entering the ear canal of the user from the environment. The ear cushion further comprising an annular exterior surface and an annular interior surface each extending from the contact surface to the attachment surface and facing respectively the environment and the ear canal of the user when the user is wearing the earphone in its intended position. The ear cushion further comprising a foam core (150) having a first acoustic impedance, and a cover having a first portion extending across the exterior surface and a second portion extending across the contact surface. The first portion of the cover has a second acoustic impedance that is greater than the first acoustic impedance, wherein that at least one first subportion of the second portion of the cover has a third acoustic impedance that is smaller than the second acoustic impedance.

Abstract: A computer-implemented method for transforming audio input data into audio output data is provided. The method comprises receiving audio input data, providing background sound data by separating speech components from the audio input data by using a speech removal module, determining acoustic scene data, linked to an acoustic scene matching the background sound data, by using an acoustic scene classifier module, selecting a specialized noise reduction module based on the acoustic scene data, and processing the audio input data by using the specialized noise reduction module such that the audio output data is generated.

Abstract: A method for manufacturing a hearing device is disclosed. The hearing device comprises a speaker, a first chamber, and a sound channel arranged between the first chamber and the surroundings of the hearing device or a second chamber. An element of a thermoplastic material being in a solid state is arranged in the sound channel. A laser light is applied to the element to thereby activate the element to change from the solid state to a liquid state. The element then changes from the solid state to the liquid state filling out a cross-section of the sound channel and thereby sealing the sound channel. Finally, cooling of the element is allowed leading to a change of the element from the liquid state to solid state while filling out the cross-section of the sound channel.
