Measurement of the Psychological Annoyance of Simulated Explosion Sequences.

Abstract

An explosion and explosion-sequence simulator was developed in the laboratories of Stanford Research Institute in Menlo Park, California. The simulator produces vibrations and sounds similar to those that would be experienced by people inside a typical frame dwelling located 1-3 km from an explosion site. Ten adult subjects were exposed to the sounds and vibrations caused by six different simulated explosions and explosion sequences. The concomitant psychological annoyance was measured by the method of magnitude estimation with a jet aircraft noise as a scalar reference. Six physical measures of the noises were obtained and were used to correlate with the psychological measures. Total energy measures, weighted spectrally by D1- and D2-type weights, were found to be the best physical predictors of psychological annoyance. In this pilot experiment it was also found that annoyance judgements of simulated explosions and explosion sequences were probably less reliable than similar judgements of the annoyance of aircraft noises.
