Embodiment Construction

[0141] The novel binaural hearing aid system will now be described more fully hereinafter with reference to the accompanying drawings, in which various examples are shown. The drawings are schematic and simplified for clarity and only show details necessary for understanding the invention, while other details have been omitted. The appended patent claims can be implemented in different forms not shown in the drawings and should not be construed as limited to the examples given here. Rather, these examples are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the appended patent claims to those skilled in the art.

[0142] Like reference numerals refer to like elements throughout.

[0143] figure 1 is a simplified block diagram of one of the digital hearing aids 10 of the novel binaural hearing aid system. The hearing aid 10 comprises: an input transducer 12, preferably a microphone; an analog-to-digital (A / D) converter 14 for...

Abstract

Provided is a wireless binaural compressor. New binaural hearing aid systems and methods are provided in which binaural processing of input sound is performed based on wireless transmission of data between the hearing aids of the system with a low data rate and therefore with low power consumption, and wherein each of the hearing aids of the system comprises a microphone and an A / D converter for provision of a digital input signal in response to sound signals received at the respective microphone, a signal level detector for determining and outputting a signal level that is a first function of the digital input signal, a signal parameter detector for determining and outputting a signal parameter that is a second function of a signal in the hearing aid, a transceiver for wireless data communication of the signal parameter with the other hearing aid, a processor that is configured to process the digital input signal in accordance with a selected signal processing algorithm into a processed digital output signal, including a compressor for compensation of dynamic range hearing loss based on the signal level, and a D / A converter and an output transducer for conversion of the processed digital output signal to an acoustic output signal, and wherein the gain of the compressor is controlled by a compressor control signal and wireless data communication is performed at a data transmission rate with a longer time period between trigger and release time periods of the compressors.

Description

technical field [0001] A binaural hearing aid system with wireless data transmission between two hearing aids is disclosed below, and wherein compression for compensation of hearing loss in one hearing aid's dynamic range is performed on the basis of signal parameters received from the other hearing aid , in order to provide coordinated binaural compression in both hearing aids, whereby even in the time period between successive transmissions of signal parameters that are longer than the attack and release times of the compressors performed at the data transfer rate in the binaural hearing aids The system's data transfer between hearing aids also improves binaural hearing. Background technique [0002] Hearing-impaired people are usually affected by a frequency-dependent and sound-level-dependent loss of hearing sensitivity. Therefore, a hearing-impaired person can also hear certain frequencies (for example, low frequencies) as well as a person with normal hearing, but cann...
