Reverberation Time Measurements in the NASA Langley Exterior Effects Room (Eer)

By: Nasa, National Aeronautics and Space Adm

One-third octave band background noise and reverberation time measurements were conducted in the Exterior Effect Room (EER) at the NASA Langley Research Center. The related overall acoustic absorption of the room was calculated. The acoustic field in the room was characterized. Reverberation time measurements were performed using the integrated impulse response method. The results were compared with independent measurements using the interrupted noise reverberation time method and different instrumentation. Reasonable agreement was obtained between the reverberation times of the two methods.Grosveld, Ferdinand W.Langley Research CenterREVERBERATION; BACKGROUND NOISE; ACOUSTIC ATTENUATION; OCTAVES; ACOUSTICS; NOISE MEASUREMENT; TIME MEASUREMENT; SOUND FIELDS; ABSORPTIVITY
