Sep 13, 2019 . The Acoustic Research Complex (ARC) is a unique facility operated by the Air Force Research Laboratory (AFRL) on WSMR. The ARC facility is the first of its kind within DoD and the research community as a whole. It is used to help with the design, modification, and increasing combat survivability of current and future aircraft. The ARC provides ...

The evaluation measurements at fixed SNRs resulted in a mean speech reception threshold (SRT) of - 7.3 ± 0.2 dB SNR and slope of 13.3 ± 1.2 %/dB. The major training effect of 1.5 dB was observed for the first two consecutive measurements. Mean SRTs of - 6.7 ± 0.7 dB SNR and - 7.4 ± 0.7 dB SNR were found from the third to the sixth adaptive ...

Abstract: The MARL collection is dedicated to the study of all aspects of musical acoustics. The collection, established in 1996, came about through the joint effort of the representatives of the Catgut Acoustical Society (CAS), founded by Carleen M. Hutchins and devoted to the study of violin making; Stanford’s Center for Computer Research in Music Acoustics (CCRMA), and Virginia Benade ...

Acoustic theory is a scientific field that relates to the description of sound waves. It derives from fluid dynamics. See acoustics for the engineering approach.
Acoustic signals are functions of time in which the output is a pressure or a velocity potential response. An acoustic signal is a⁄ected by the environment in which it propagates, so one can attempt to remove the environmental e⁄ects to extract the useful information, in this case the original signal.
Acoustics is the branch of physics that deals with the study of all mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound.
