Abstract

A communication system for communication in harsh environments includes a hearing protection headset with left and right earcups. Each earcup comprises a speaker unit, a cavity with an opening adapted for the user's ear, and a flexible seal for acoustic sealing. The earcups provide passive sound attenuation, reducing external noise. The headset features an adaptor element with a central void and a rim that, when inserted between the earcup and flexible seal, increases the cavity volume for enhanced sound attenuation. The headset also includes an active noise reduction (ANR) circuit that generates anti-noise signals to cancel out external noise. The ANR circuit operates in two modes, depending on whether the adaptor element is inserted or not.
