Issued: February 19, 2013
Filed: May 24, 2010
Term Extension: 275 days

Inventor: John W. Parkins (Ithaca, NY)
Assignee: Red Tail Hawk Corporation (Ithaca, NY)


A talk-through system for hearing protectors such as headphones, helmets, earplugs and the like, in which separate left and right microphones are controlled by separate left and right switches. The microphones allow ambient sound to be heard by the wearer of the hearing protector, and normally the wearer hears audio from both microphones in the appropriate ears. Pushing a switch causes the audio from the ear on which the switch is mounted to be enhanced and, preferably, switched to both ears. Various arrangements of control logic are provided such that activation of a switch can cause changes in audio processing.
