When people hear sounds through sound system, perceptive loudness of each sound pressure level varies with each level. This difference causes some confusion in adjusting volume level and designing the volume level of sound systems. According to previous studies, it is known that perceptive sensitivity of variation in sound pressure level depends on the sound pressure level and frequency of sound source. However, quantitative analysis on user’s perceptive sensitivity of sound level which they actually perceive from the change of sound pressure level has not been studied yet. This study aims to understand the perceptive sensitivity of variation in sound pressure level for some specific frequency bands. To this end, 118 sound samples (frequencies: 500 ㎐, 1 ㎑, 2 ㎑, sound pressure levels: from 40㏈ SPL to 100㏈ SPL) were evaluated by 27 participants (male: 17, female: 10) in the condition of driving automobile. Based on the results of subjective ratings of unit change of sound pressure level and 2㏈ SPL, the characteristics of perceptive sensitivity of variation in sound pressure level were identified. Also, through curve fitting analysis of the subjective rating results, perceptive sensitivity curves of each frequency were estimated. According to the results, when frequency is high, the perceptive sensitivity tends to be more sensitive than the case of low frequency and the sensitivity curve was estimated to have cubic relation. These results could be used to adjust the volume level of sound system in automobile to meet customer’s perceptive characteristics and needs.
