Acoustic performance assessment of residential buildings – A measurement and survey study

Abstract

The "Noise Protection and Sound Insulation in Buildings" regulation issued by the Turkish Ministry of Environment and Urbanization, aims to organize the requirements and enforcements for noise control in buildings. This regulation introduces a performance classification scheme for residential buildings that ranges from A to F similar to that is proposed in the draft standard ISO-CD19488. Acoustical performance class is assigned based on six acoustical performance parameters: airborne and impact sound insulation, façade sound insulation, indoor background noise levels, mechanical noise levels and reverberation time. Aiming to confirm the applicability of the limit values and the classification system, a case study was performed by selecting three sample buildings. Airborne and impact sound insulation of building elements, reverberation time and indoor noise levels were measured starting from 100 Hz and 50 Hz and the results were compared with the regulatory requirements. Simultaneously, a survey was also conducted applying a questionnaire specifically prepared to evaluate the residents’ opinions in terms of satisfaction/dissatisfaction about acoustic performance of their dwellings. The relationships between the occupants’ assessments and the regulatory requirements are discussed in this paper. © 25th International Congress on Sound and Vibration 2018, ICSV 2018: Hiroshima Calling.
