PSYCHOPHYSICS AND ITS APPLICATIONS - LOUDNESS OF NON-STEADY STATE SOUNDS -

  • Seiichiro Namba

Abstract

Basic research into psychoacoustics and its application is discussed. The psychophysical law should be robust in order to be applied to practical purposes. The importance to use appropriate psychophysical methods according to the purpose of the study and the necessity to develop new methods will be introduced. Various problems have to be considered when the findings in laboratory experiments are applied to real life situations. They are, for example, to control complicated variables keeping the reliability of the experiments for practical application, to cover wide area from static stimuli to dynamic stimuli and the necessity to take the effects of cognitive factors and ecological validity into consideration. A series of the process from basic research of psychoacoustics to its application was introduced using the loudness of non-steady state sounds as an example.
