A statistical model for predicting the probability of complaints from Army weapons noise. ” Judgments of the relative unacceptability of subsonic aircraft flyovers and sonic booms in Kryter et al.'s () Edwards Air Force Base study showed that an increase of 12 PNdB in the intensity of sound produced by a subsonic aircraft was equivalent to about a 6 dB increase (from 1 to 2 pounds per square foot) in the intensity of a sonic boom.

Summary of recent NASA studies of human response to sonic booms Article in The Journal of the Acoustical Society of America (1 Pt 2) · February. ABSTRACT This study was undertaken to evaluate subjective and objective aspects of moderate levels of noise from impulsive sources.

The study excluded evaluation of hearing damage risk or annoyance from building vibration by high level impulsive noise, which were covered by recent recommendations of the National Research Council, Committee on Hearing Bioacoustics and.

The influence of procedural fairness on evaluations of noise annoyance caused by sonic booms predicted for these two classes of vehicles. The laboratory study is conducted in two sonic boom. Abstract. In the last two decades, community noise has become a problem of major dimensions in many countries.

Increasing numbers of people are exposed to noise generally present in their residential and working environments; the level of this general noise has risen steadily along with the state of machine technology, especially in the transportation virtuosobs.com: W.

The use of sound exposure level is recommended to facilitate combination of data when more than one impulse noise event occurs per day, as is usually the case.

Further, it is consistent with subjective evaluations of sonic booms where duration of the signal influences subjective response [34].
