Project Description

Acoustic Monitoring for Spaceflight Vehicle Applications
This SBIR will develop and demonstrate acoustic sensor technology enabling real-time, remotely performed measuring and monitoring of sound pressure levels and noise exposure levels in long-duration space vehicles. The acoustic sensor technology developed will enable a network of continuously monitored, real-time acoustic sensors providing sound pressure level information as a function of frequency and/or time at multiple locations for the current International Space Station (ISS) and future long duration spaceflight missions. The phase I will show the feasibility for the phase II to develop the software and hardware of an acoustic monitor to a TRL 6 level. In phase II a demonstration unit and it software package will be delivered to NASA for their testing. A phase II demonstration will be done in JSC Acoustics and Noise Control Lab (ANCL) so that testing can be performed in the ISS Acoustic Mockup. More »
