Abstract:
This research investigated psychological and physiological responses to floor impact noise. It consists of six studies. The first study carried out 24-hour noise measurements inside real residences in multi-family housing buildings. Different airborne and structure-borne noise sources, and their characteristics (e.g. noise level) were identified. Slab thickness did not have any correlation with the noise characteristics. It implies that although the slab thickness is an important factor, other physical characteristics and upstairs neighbours' activities are also important determinants. The second and third studies measured psychological and physiological responses to floor impact noise in laboratory settings. Real and standard impact noise sources (e.g. human footsteps and the impact ball) were used as stimuli. Noticeability and annoyance increased as the noise level increased. There were significant differences between real and standard impact noise exposure in the noticeability and annoyance. The noise exposure also changed the physiological responses. In addition, self-reported noise sensitivity had significant impacts on the responses; greater responses were shown by the high noise-sensitivity group. The fourth study investigated emotions evoked by the floor impact noise. Emotion lexicons were collected from previous interview transcripts and online postings. The lexicons were then sampled and clustered into grouped through survey studies. Four emotion clusters (anger, dislike, pain, and empathy) were examined in a laboratory study when the noise stimuli were presented. The results showed that the emotions had strong correlations with the noise level and annoyance. Noise sensitivity and attitude towards neighbours showed significant influences on the responses. The fifth study tested those found so far in the previous chapters. Their psychological responses to indoor noise (e.g. annoyance) were found to be influenced by various factors (e.g. noise sensitivity). Outdoor noise level did not have any masking effect on the indoor noise responses. In addition, the psychological responses to indoor noise had significant effects on blood pressure and health-related quality of life. The sixth study investigated the relationship between residents' attitudes towards neighbours and their coping strategies. Of many conditions which may influence their attitudes and copings, the chapter particularly highlights three conditions: attitudes shown by the neighbours, past experience/history, and predictability/uncertainty.
