Design of a Self-Contained Acoustical Testing Facility 2011-01-1642
This paper presents an overview of the acoustical design of a small volume self-contained acoustical testing facility (SCATF). The design focuses on a small volume (25 m₃) reverberation room for testing the random incidence sound absorption performance of small samples of acoustical materials and automotive parts. This reverberation room also couples to a small volume hemi-anechoic room and serves as the random incidence source room for sound transmission loss testing. These testing approaches respectively target the SAE J2883 (pending) and J1400 test standards.
