摘要： A hearing device (2) and a method for customizing audio signal processing of the hearing device (2) are described. The hearing device (2) is configured for audio signal processing of an input audio signal (I) to obtain an output audio signal (O), using an acoustic scene classification unit (12) for classifying the input audio signal (I) to belong to one or more acoustic scene classes from a set of acoustic scene classes. For customizing the audio signal processing, at least one audio signal sample of an acoustic environment is provided to an embedding neural network (14) of the acoustic scene classification unit (12). A sample embedding for each audio signal sample is determined using the embedding neural network (14). The audio signal processing is customized by retraining at least one classifier (15) of the acoustic scene classification unit (12) using the sample embeddings, thereby adding an acoustic scene class for the acoustic environment to the set of acoustic scene classes.

摘要： Disclosed is an annular ear cushion (100, 100') for an earphone (210, 210') configured to be worn at an ear of a user. The ear cushion (100, 100') is configured to abut the head of the user along an annular contact surface (110, 110') of the ear cushion (100, 100') and to abut or face a housing (220, 220') of the earphone (210, 210') along an annular attachment surface (120) of the ear cushion (100, 100') when the user is wearing the earphone (210, 210') in its intended position, thereby reducing the level of sound entering the ear canal of the user from the environment. The ear cushion (100, 100') further comprising an annular exterior surface (130, 130') and an annular interior surface (140) each extending from the contact surface (110, 110') to the attachment surface (120) and facing respectively the environment and the ear canal of the user when the user is wearing the earphone (210, 210') in its intended position. The ear cushion (100, 100') further comprising a foam core (150) having a first acoustic impedance, and a cover (160) having a first portion (162) extending across the exterior surface (130, 130') and a second portion (164) extending across the contact surface (110, 110'). The first portion (162) of the cover (160) has a second acoustic impedance that is greater than the first acoustic impedance, wherein that at least one first subportion (166) of the second portion (164) of the cover (160) has a third acoustic impedance that is smaller than the second acoustic impedance.
