USAARL NUH-60FS Acoustic Characterization
Abstract
The United States Army Aeromedical Research Laboratory (USAARL) Auditory Protection and Performance Division (APPD) previously acoustically characterized the Black Hawk flight simulator (NUH-60FS). Since that characterization, the NUH-60FS underwent upgrades and modifications, leading to the possibility that the previous characterization may no longer be accurate. Measurements of the NUH-60FS examined the base speakers and higher-level speakers at five different noise-level settings. The base speakers yielded lower levels across the third octave band levels from 31.5 Hertz (Hz) to 8000 Hz, while the higher-level speakers had some levels lower and some levels higher. For the pilot seats, research participants should wear hearing protection for levels greater than one with the base speakers and for all levels with the higher-level speakers while the flight simulator is in operation. For the two rear positions, the levels change to greater than three for the base speakers and greater than one for higher-level speakers.
