Abstract
Systems and methods for reducing wind noise in an electronic hearing protector are provided. The electronic hearing protector includes a housing and a windscreen. The housing includes a cut-out portion having at least one acoustic inlet. The windscreen covers the cut-out portion and includes an outer surface. An acoustic path within the cut-out portion from an effective center of the acoustic inlet(s) to the windscreen is at least 100 degrees. A minimum distance from the effective center of the acoustic inlet(s) to the outer surface of the windscreen is at least 2.5 millimeters. In various embodiments, the electronic hearing protector may include a high-level limiter disposed in the housing. The high-level limiter selectively attenuates a frequency below a voice range more than a frequency in the voice range of a microphone input signal to provide a signal output with noise reduction at frequencies outside of the voice range.
