Since People have serveral feelings for the sound according to its frequency the responses of sound frequencies for the people have been studies in this paper. The feelings of sound are investigated by questionaire thar are pure tones, waring sounds of automobile and sounds that white noise is passed by one and one-third octave bandpass filter. Experimental results have been shown that people have good response for the pure tone between 160(Hz) and 500(Hz), and have unpleasant response for the pure tone above 1000 (Hz), warning sounds of automobile, and for white noise. Warning sound of automobile horn has been mainly distributed between 1000(Hz) and 2600(Hz). Hence the resells are shown that the responses for warning sound of autombile horn are similar to that for pure tone between 100(Hz) and 2600(Hz). As a results, it is necessary to make warning sound of automobile horn have frequencies between 200(Hz) and 500(Hz) with low level in the residental districts and crowded streets.
