Project Number: 004
This project seeks to better understand and improve the tools used to measure noise level reduction experienced by buildings exposed to aircraft noise.
One research group has assessed whether using a phased array of microphones is an effective way to measure noise level reductions. A second group has evaluated measurement of noise level reduction with the use of loudspeakers to simulate aircraft flyover noise at a test house. The results may be used to compare various noise level reduction estimation methods.
