Of the daily noises, construction noises cause serious conflicts between a construction firm and residents due to their high sound pressure level and shocking, repetitive 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. However, since construction noises are characterized by very diverse spectra and waveforms, it has been indicated that they cannot be reflected only by physical loudness: SPLdB(A). In addition, the need to reflect acoustic psychological characteristics and meanings of human beings in evaluating construction noises has recently been indicated. This study aimed to use six Zwicker parameters to determine the sound quality and acoustic psychological characteristics of construction noises and analyze the correlation between physical indexes of construction noises, as found in literature review, and the Zwicker parameters. Loudness of construction noises were closely correlated with SPLdB(A); shocking noises were perceived as ‘loud, sharp, and annoying’ sound. The Zwicker parameters were most strongly correlated with loudness, followed by unbiased annoyance and sharpness, among the evaluation indexes; as for correlation with construction noises, ‘normal noises’ were closely correlated with loudness, ‘shocking noises’ were closely correlated with loudness, unbiased annoyance, and sharpness, and ‘fluctuating noises’ were closely correlated with loudness. Therefore, if loudness, unbiased annoyance, and sharpness were taken into account in terms of the sound quality in evaluating construction noises, it is expected to be useful to make and revise criteria for regulating the noises.
