| Research Abstract |
In Japan, the environmental noise problem, that is one of the familiar sensory pollutions, is still serious. In order to improve the problem, it is important that the method of assessing intermittent noise, impulsive noise and tonal components in environmental noise is established. Further, a measure and a prediction of the noise are also needed as well as the assessment. The some investigation for the impulsive noise has been started in our laboratory. In this study, field measurement of tonal component in environmental noise and subjective experiment using simulated sound field in acoustic laboratory were performed. From the results, the applicability of the evaluation values based on energy used the world over was investigated.
