Abstract: A hearing protection device (100) includes at least a first audio signal processor (P1) with a first audio signal frequency filter (F1) and a first audio signal compressor (C1) and a second audio signal processor (Pn) with a second audio signal frequency filter (Fn) and a second audio signal compressor (Cn), the first audio signal processor and the second audio signal processor arranged in parallel, the first audio signal processor adapted to pass audio signals within a first frequency range and to compress the passed audio signals when the volume of the passed audio signals is above a first threshold volume, and the second audio signal processor adapted to pass audio signals within a second frequency range and to compress the passed audio signals when the volume of the audio signals is above a second threshold volume.

Abstract: The present application is directed to a hearing aid apparatus for wearing use by a user, including a frontend sound collector configured to collect a frontend signal; a backend sound collector configured to collect a backend signal; and a sound processor configured to process the frontend signal and the backend signal; wherein the sound processor includes a frontend delayer configured to apply a delay coefficient to the frontend signal to produce a delayed frontend signal; a backend delayer configured to apply the delay coefficient to the backend signal to produce a delayed backend signal; and an adaptive filter configured to process the delayed frontend signal and the delayed backend signal to produce an adaptive filter output signal.

Abstract: A hearing aid frontend device for frontend processing of ambient sounds. The frontend device is adapted for wearing use by a user and comprises first and second sound collectors adapted for collecting ambient sound with spatial diversity. The sounds collected by the sound collectors are processed by a sound processor. The sound process comprises a digital signal processor for beamforming sounds collected by the first and second collectors, and the processed sounds are subsequently subject to adaptive noise cancellation.

Abstract: A hearing kit for use with a hearing device applying fixed beamforming technology, comprising a first end portion, a first microphone disposed at the first end portion, a second end portion, and a second microphone disposed at the second end portion. An elongated third portion is disposed between the first and second end portions for resting on the user's neck, adapted to position the first and second microphones on the left and right sides of the user at the same level. The first and second microphones are adapted to face outward toward the same direction in use. A processing unit is adapted to process signals received from the microphones and transmit processed signals to the hearing device. The microphones face toward the same direction of the user for receiving the listening sound.
