Abstract
A human wearable mask includes a skirt for directly contacting a human wearer and a sound conduction component on the skirt. The sound conduction component can provide an alert notification within high-noise environments while allowing ambient sounds to be heard over the conduction speakers. The sound conduction component may be used to reproduce audio for firefighters and other users who need radio communications.
