Embodiment Construction

[0040] figure 1 A schematic representation of the behind-the-ear hearing aid 1'according to the prior art. It includes a housing 2'with a hearing aid ear hook 5'behind the ear wings 12' of the hearing aid carrier. In addition to the electronic components combined into the signal processing unit 9', the housing 2'is also equipped with a microphone 3', a battery 8'and an earpiece 4'. The acoustic signal generated by the earpiece 4'is transmitted to the ear piece 7'installed in the ear canal 13' of the hearing aid carrier through the hearing aid ear hook 5'and the acoustic hose 6'. A control element 10', such as an on-off switch or a working mode regulator, is installed on the hearing aid housing 2', which is connected to the signal processing unit 9'.

[0041] figure 2 For example, the frequency characteristic 20 of the comb filter is shown. It represents the variation curve of the amplitude 22 with the frequency 21, the unit of amplitude is, for example, decibel, and the unit o...

Abstract

A method of operating a hearing device monitors for a head movement of a hearing device wearer. When a head movement is detected, an acoustic signal acquired by a microphone is output in an amplified and phase-modulated manner with a receiver. Furthermore, a hearing device includes a motion sensor and a signal processing unit that is configured to execute the method.

Description

Technical field [0001] The invention relates to a working method of a hearing aid that reduces the perception of a comb filter. In addition, the present invention also relates to a hearing aid that reduces the perception of the comb filter. Background technique [0002] Hearing aids are used to provide surrounding sound signals to the hearing impaired. In order to compensate or treat their respective hearing defects, these sound signals must be processed and enhanced. In principle, hearing aids include one or more input converters, a signal processing unit with an amplifier or amplifier, and an output converter. The input converter is usually an acoustic receiver, such as a microphone, and / or an electromagnetic receiver, such as an induction coil. The output converter is generally designed as an electro-acoustic converter, such as a small amplifier, or an electromagnetic converter, such as a bone conduction earphone. It is also called a headset or earpiece. The output convert...
