The comparison of psychological evaluation between military aircraft noise and civil aircraft noise

摘要

It is reported that community response to military aircraft noise is severer than that to civil aircraft noise in some former studies. In the present study, psychological experiments were conducted including the stimuli of military aircraft noise and civil aircraft noise. Participants were not informed whether each noise source was a military or civil aircraft. It was found that perceived noisiness and subjective annoyance to aircraft noises were almost the same between noises from military and civil aircraft when single-event, A-weighted sound exposure levels were equal. This suggests that participants did not distinguish between military and civil aircraft noise. These results imply that overestimation of military aircraft noise is caused by not only acoustic properties but also non-acoustic factors, such as attitude toward military aircraft noise.
