Abstract
First responders operate in challenging acoustic environments where noise, alarms, engines, radio communications, and communications to others in the environment make voice communications with hands-free, voice operated switch (VOX) operation difficult. Broad Digital will use a combination of passive acoustic design, noise suppression and subtraction, signal separation, and equalization to provide clear speech for audio communications and robust VOX operation. Broad Digital will combine this with adaptive gain control, compression, equalization, and noise cancellation for intelligible, clear speech to the responder's headset. This combination of algorithms will allow the first responder to hear, and be heard, using VOX operation while saving lives in these challenging environments. This development will provide the core technologies for improvements to military radio handsets and headsets and for other commercial communications systems.
