- means for detecting a sound pressure level of an inputted sound;
means for measuring a rate of increase of the detected sound pressure level;
means for comparing the measured rate of increase of the detected sound pressure level with a predetermined value and selecting a first period of time from a preselected range in accordance with the comparisonmeans for measuring a second period of time when the detected sound pressure level exceeds a predetermined sound pressure level;
means for commencing the first period of time simultaneously with the second period of time; and
