Generating Voice Intelligibility and Quality Test Material in Simulated Acoustic Noise ABSTRACT In 1989 an effort was initiated to provide the capability for the USAF’s RL/EEV office to generate voice intelligibility and quality test material in acoustic backgrounds representing platforms of interest to DoD. Specific material was to include master audio tapes for the implementation of the Diagnostic Rhyme Test (DRT) and the Diagnostic Acceptability Measure (DAM). RL/EEV intended to record noise environments in the field, reproduce them in an acoustic isolation chamber, and record various talkers in that chamber speaking over a microphone resident to the simulated environment. |
