Abstract: A communication system is provided having at least one earpiece (14, 114, 214) including a loudspeaker (26) for stimulating a user's hearing according to audio signals supplied to the earpiece; a voice microphone arrangement (28, 58, 60, 62, 258, 260) for picking up the user's voice; a configurable audio interface (22, 32, 34, 36, 38) for exchanging audio signals with an external wireless communication device (24) selected from a plurality of different types of external wireless communication devices; and a configuration interface (40) for adapting the configuration of the audio interface to the selected type of the external wireless communication device by an external configuration device (18).

Abstract: An active hearing protecting system right earplug and a left earplug and a wearable central unit to be worn at the user's body a digital audio signal processing unit which has at least two channels and which can be connected via an audio input to an external audio signal source each earplug including a microphone and a loudspeaker which are connected to the audio signal processing unit. The central unit also has a detector for detecting audio signals and being adapted to control the audio signal processing unit when audio signal is detected.

Abstract: A method and system for data logging in a listening device is provided. The system includes a digital signal processing (DSP) entity, which performs normal hearing aid audio and system processing, a level translating module, and a non-volatile (NV) memory. The NV memory is used to store logged data. During the hearing aid audio processing, the DSP entity communicates with the NV memory via the level translating module. The level translating module performs voltage-translation during data logging to a communication signal between the DSP entity and the NV memory.

Abstract: A system for separation of a user's voice from ambient sound, comprising a device to be worn at the user's ear or at least partly in the user's ear canal comprising a first microphone oriented outwardly towards the environment and a second microphone oriented inwardly towards the user's ear canal, and an audio signal processing unit for processing audio signals from the first and second microphone by a blind source separation algorithm adapted to separate the user's voice from ambient sound.
