Environmental acoustics update

Abstract

This is the oral paper of a plenary lecture presented at the opening ceremony of the Joint meeting of the Acoustical Societies of Japan and America. The paper has briefly reviewed the update of both public and personal aspects of 'Environmental acoustics.' Although it has interdisciplinary or multidisciplinary nature, it is limited arbitrarily to those aspect related to people's daily lives, particularly those in which the author has an interest. The environment can be defined as the interface between human beings and everything surrounding them, i.e. the human Psycho-physiological factors and surrounding Physical factors. Therefore it seems to be imperative to promote Psycho-physiological research for developing environmental acoustics.
