    Interaction between annoyance, indoor noise levels and acoustic classification of buildings
    (The Institute of Noise Control Engineering of the USA, Inc., 2022) Kurra, S.; Dumen, A.S.
    Assessment of annoyance “at home” from environmental noises has been widely investigated so far and the ISO/TS 15666:2021 was developed to lead the socio-acoustic surveys. On the other hand, the rating of buildings' acoustical performance considering the indoor noise levels, has also been well researched in building acoustics and the studies have ended up with the ISO/TS 19488:2021 covering the acoustic classification system for buildings. Basically the rating system needs to be supported by the subjective tests in the field or in laboratories, to acquire data about the annoyance/disturbance or satisfaction of residents. If the target is to design the healthy, comfortable and sustainable acoustical environment, both technical standards might be harmonized in the future, particularly with respect to survey methodologies and evaluations. In this paper, based on the dose/response relationships with respect to the indoor noise levels, an approach is proposed to translate the acoustic classes proposed in ISO/TS 19488, into the annoyance boundaries in terms of different scales (verbal/numerical and the HA%) referred in ISO/TS 15666. The results from the previous laboratory and the field studies conducted by the authors, were used for verification of this approach. © 2022 Internoise 2022 - 51st International Congress and Exposition on Noise Control Engineering.

    NEIGHBOUR NOISE IN MULTI-STOREY HOUSING WITH POOR SOUND INSULATION-FACTS AND OCCUPANTS' VIEWPOINTS
    (European Acoustics Association, EAA, 2023) Dumen, A.S.; Rasmussen, B.
    Neighbour noise has a significant role in acoustic privacy, protection and indoor environmental quality in residential buildings. Estimation of annoyance due to neighbour noise and concluding dose-response relationships are challenging due to variety in noise characteristics, occupant perceptions and other individual factors such as attitudes against the noise sources. This study uses qualitative analysis to examine complaints, attitudes and viewpoints on neighbour noise. In February 2021, an article was published in a national newspaper (Jyllands-Posten) of Denmark on the topics of implementation of acoustic labelling and sound insulation improvement. The article was also shared as social media posts in newspaper's official account and it received high public interest and several comments. People's reactions were gathered from the Facebook pages and analysed qualitatively. More than 500 comments were received in total, and these were grouped according to agreement/disagreement with classification, noise complaints (noise sources/activities, building definition, exposure timeframe, measures taken) accountable parties, emotions, beliefs and suggested measures and/or actions. © 2023 Ayca Sentop Dumen ayca.sentop@bilgi.edu.tr & Birgit Rasmussen bira@build.aau.dk This is an open-access article distributed under the terms of the Creative Commons Attribution 3.0 Unported License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.
