ARL Acoustic Measurement in Buildings 518 and 520 at APG

Abstract

Acoustic measurements, including sound pressure levels, reverberation times, and patterns of early reflections, were made in all of the laboratory spaces used for acoustic research in the Visual and Auditory Processes Branch of the Human Factors and Engineering Directorate of the U.S. Army Research Laboratory (ARL). Reported are the data for five laboratory areas housing ten individual test chambers. These laboratory areas are situated in buildings 518 and 520 on Aberdeen Proving Ground, Maryland. Measurements were made with a Casella CEL Ltd 573.C1R sound level meter and the MLSSA (maximum length sequence system analyzer ) low sound analysis software and sound card. The purpose of this report is to document the technical characteristics of the acoustic spaces used for auditory research and simulation studies at ARL
