Understanding human responses to sounds might be helpful, e.g., in solving cases of noise annoyance or sound optimization. Evaluation of sounds by questionnaire as well as measuring physiological responses might supply useful information here. Previous laboratory studies exposing young male students to different vehicle pass-by noises (L eq = 83 dBA) showed that for some sounds physiological arousal was combined with a more positive evaluation. In the present study, the same sounds were presented to four groups of subjects (n = 66) differing in age and sex. Depending on age, sex, and some other personality traits, the results show clear differences in the physiological responses as well as in the subjective evaluation of the sounds. Besides of biological differences in reactions, different patterns of response have to be discussed which are obviously distributed unevenly among the four groups. Source
