Abstract

The present disclosure provides a hearing protection system and a method for estimating a voice signal of a hearing protection system user. The hearing protection system comprises an ear canal microphone for provision of an ear canal input signal; a receiver for provision of an audio output signal; a compensation module for receiving and filtering the ear canal output signal for provision of a compensation signal; and a mixer connected to the ear canal microphone and the compensation module for provision of a voice signal, wherein the compensation module comprises a filter controller, a primary filter and a secondary filter, wherein the primary filter is a static filter, wherein primary filter coefficients of the primary filter are static, and wherein the secondary filter is an adaptive filter, wherein secondary filter coefficients of the secondary filter are controlled by the filter controller based on the voice signal.

Description

technical field [0001] The present disclosure relates to hearing protection systems and related methods including methods of estimating speech signals. Background technique [0002] In noisy environments, it may be desirable for a user to protect his / her hearing while enabling the user to communicate with others via wireless communication. Further, it can be challenging to pick up and separate the user's own voice from ambient sounds and / or audio played by the receiver of the hearing protection system. Contents of the invention [0003] Accordingly, there is a need for hearing protection devices and methods with improved estimation and / or detection of user voice signals of hearing protection device users. [0004] A hearing protection system is disclosed, the hearing protection system includes: an ear canal microphone, used to provide an ear canal input signal; a receiver, used to provide an audio output signal based on the ear canal output signal; a compensation module, ...
