Abstract
The present study investigates the adverse effects of floor impact noise using both subjective and physiological methods. A total of 21 subjects participated in the experiments and they were instructed to press a button when they noticed a sound and rate noise annoyance. Heart rate (HR), electrodermal activity (EDA), and respiration rate (RR) were measured while subjects were exposed to floor impact sounds induced by real impact sources and standard heavyweight impact source (impact ball). It was found that noise annoyance and noticeability were highly correlated with noise levels. The floor impact sounds caused by impact ball was found to be more noticeable than real impact sounds when A-weighted maximum noise levels (LAFmax) were greater than 35 dBA. The results showed that listening to floor impact noise lowered HR and raised EDA and RR. The results also indicated that EDA and RR were significantly affected by noise levels.
