The effects of auditory stimuli with varying frequency and intensitiy on human simple reaction time

Abstract

Several studies have been performed on the reaction time stimuli of different modalities in man. However, studies concerned with how ‘Simple Reaction Time' (SRT) is affected by auditory stimuli with different intensities and frequencies are rare. In this study, we aimed at determining the pure sound tone of which frequency and intensity affects SRT the most. For this purpose, the subjects were classified according to age and sex and SRTs were measured by changing the sound intensity and frequency one at a time. Healthy male and female adults, aged between 17 and 24 (mean age: 20.65 yrs in both groups) were included in the study. Sound frequencies used were 500 Hz, 1 kHz, 2 kHz and 4 kHz. Each pure tone was applied at three different intensities; 60, 70 and 80 dB. It was observed that SRT gets shorter statistically significantly as the stimulus intensity is increased and that SRT changes significantly with frequency. The mean reaction time of all subjects regardless of sex for all intensities was calculated. It was shortest for 500 Hz and longest for 2 kHz. It has been concluded that among the stimuli used in this study the tone beep with a frequency of 500 Hz and intensity level 80 dB is the most effective stimulus which causes the shortest auditory reaction time in our subjects. Simple reaction times of all subjects regardless of gender to all stimuli fell in the range of 160- 190 ms.
