Noises in each construction field cause residents in the neighborhood to make complaints due to their high sound pressure level and repetitive, shocking sound. While South Korea regulates construction noises on the basis of legal criteria to minimize the damage from the noises, the regulation only involves a weighted sound level (dB(A)), which is loudness, like other types of noises. It is therefore necessary to make typology of construction noise sources and evaluation vocabularies with the objective of making criteria for regulating construction noises suitable for the South Korean situation. While research based on a survey has been conducted to make typology of construction noise sources and evaluation vocabularies, there have been lots of difficulties in using it to make criteria for regulation because no consideration was given to psychological responses of people. On the basis of the findings from literature review, this study aimed to make typology of construction noise sources and vocabularies through a psycho-acoustic experiment and analyze the psychological characteristics and meanings of construction noises more accurately. The respondents’ psychological responses to construction noise sources were grouped into three factors ‘normal, shocking, and fluctuating noises’ and into ― ― six factors ‘annoying,’ ‘loud,’ ‘confusing,’ ‘noisy,’ ‘alarming,’ and ‘boisterous’ in terms of evaluation ― ― vocabularies. Since the factor with the biggest eigenvalue drawn from the respondents’ psychological responses is most important, the most important influential factor in evaluating construction noises was ‘normal noises’ for construction noise sources and ‘annoyance’ for evaluation vocabularies. This typology is expected to be useful to make and revise criteria for regulating construction noises.
