The objective of this study is to review the existing evaluation methods and to suggest fundamental data for more appropriate and creative evaluation method of sound insulation performance through psycho-acoustic experiments. As a result of the psycho-acoustic experiment for different window types, the arithmetic mean showed the highest correlation between sound insulation performance of windows and listener's subjective evaluation. Therefore, STC could be said that it is not an adequate evaluation method for windows or glasses. That's why STC has been established based on the sound insulation characteristics of a wall, it is not appropriate to evaluate that of windows which have different sound insulation characteristics.
