Abstract

<jats:p>The present study aimed to explore the effect of neighbours sounds commonly heard in wooden residential buildings on restorative EEG rhythm represented by Alpha waves. Thirty participants took part in a listening test which was performed to collect EEG data in distinct acoustics scenarios. Noise sensitivity and attitude toward neighbours were introduced as non-acoustic moderators and assessed through questionnaires before the experiment. A series of impact and airborne sounds were presented through loudspeakers and subwoofer, while participants sat comfortably in the simulated living room wearing the EEG headset (B-alert X24(r) system). The impact sound sources were two types of footsteps, adult walking and child running, recorded in a laboratory on different floor configurations and thus, varying in sound pressure level and frequency characteristics. The airborne sound sources were a lively conversation and a piece of classical piano music, digitally filtered to represent good and poor sound insulation performances of vertical partitions. The effect of sound stimuli and non-acoustic factors on restorative EEG rhythm corresponding to Alpha waves (8-13 Hz) was then analysed. Differences in response to distinct acoustic scenario were observed. Additionally, Alpha band activity showed to be affected by noise sensitivity and attitude toward neighbours of participants.</jats:p>
