An Active Noise Reduction Communication Earplug for Helicopter Crew
Agency / Branch:
DOD / ARMY
Helicopter crewmembers must function in an environment with high background noise that can cause hearing damage. With current hearing protection, excessive noise exposure may still occur in 30% of the aviation environments. We propose to extend the capabilities of the standard passive communication earplug by implementing our proven adaptive, active noise reduction (ANR) algorithms. In Phase I we package microphones within the earplug and demonstrate enhanced noise reduction performance enabled by ANR, using standard development electronics to implement the algorithms. In Phase II we focus on transitioning the algorithm implementation to electronics actually housed within the earplug while ensuring the safety and comfort of the users.
