Abstract

In the present study, the emotional reactions to commonly occurring neighbour's sounds in wooden dwellings were investigated. Listening tests were performed to assess the relationship between affective ratings and physiological parameters in distinct acoustics scenarios. Experimental work was carried out in an audiometric booth with a low background noise level. A series of impact and airborne sounds were presented through headphones and subwoofer, while the picture of a living room was shown on a monitor. The impact sound sources were an adult walking and a child running recorded in a laboratory equipped with several floor configurations. Two airborne sounds were selected, a lively conversation and a piece of classical piano music, and digitally filtered to resemble good, medium and poor sound insulation performances of vertical partitions. The experiment consisted of two sessions: in the first session, the sound sources were presented individually, while in the second one, pairs of impact and airborne sources were presented. In both sessions, affective ratings were assessed using a nine-point SAM (Self-Assessment Manikin) scale for arousal and valence. In addition, facial electromyography (f-EMG) was monitored throughout the experiment. Findings showed that increasing sound pressure level of footsteps and conversations caused an increase of arousal and a decrease of valence. Furthermore, affective ratings indicated that neighbour sounds activated the defensive motivational circuit which mediates the reactions to threat. It was observed that activity in the Corrugator Supercilii muscle group increased and activity in the Zygomaticus Major muscle group decreased when listening to impact and airborne sounds.
