E2.01 - Dual-Use Wideband Microphone Array System

NASA

Our project is a Dual-Use Wideband Microphone Array System using MEMs microphones to detect both voice and ultrasonic frequencies. The project produces a proof of concept system that monitors the condition of the spacecraft and pressurized volumes by examining the room for anomalous ultrasonic signatures (e.g. gas leaks) and alerts the severity of the problem by sonification, an audible sound, to the NASA crew. The system simultaneously provides an audio communication channel that has the ability to localize and track a speaker in a room for the crew members to talk with one another while achieving high efficiency in detecting hazards on board.
