“…In Rychtáriková et al, [3][4][5][6] a group of studies regarding the subjective perception of loudness in living environments are presented. The studies are based on rating noise types transmitted through lightweight and heavyweight wall structures, from now on denoted as LW and HW, respectively.…”

“…For instance, there are different types of building components, such as walls that offer various insulation and acoustic conditions in residencies. [3][4][5][6] In some other cases the characteristics of noise types might influence in various ways the perception of subjects: thus different standardized descriptors work better for various sound sources. [10][11][12][13] Therefore, the relation of the measured acoustic data to self-reported responses is important to study.…”

Acoustic comfort has been used in engineering to refer to conditions of low noise levels or annoyance, while current standardized methods for airborne and impact sound reduction are used to assess acoustic comfort in dwellings. However, the results and descriptors acquired from acoustic measurements do not represent the human perception of sound or comfort levels. This article is a review of laboratory studies concerning airborne sound in dwellings. Specifically, this review presents studies that approach acoustic comfort via the association of objective and subjective data in laboratory listening tests, combining airborne sound acoustic data, and subjective ratings. The presented studies are tabulated and evaluated using Bradford Hill's criteria. Many of them attempt to predict subjective noise annoyance and find the best single number quantity for that reason. The results indicate that subjective response to airborne sound is complicated and varies according to different sound stimuli. It can be associated sufficiently with airborne sound in general but different descriptors relate best to music sounds or speech stimuli. The inclusion of low frequencies down to 50 Hz in the measurements seems to weaken the association of self-reported responses to airborne sound types except for the cases of music stimuli.

“…The debate is still open and relevant research is being done on different topics such as measurement procedures at low frequencies topics [16], effect of low frequency inclusion on measurement uncertainty assessment ratings [17][18][19] and subjective/objective aspects of sound insulation descriptors [20][21][22][23], just to mention some of the most recent studies related to the harmonization of sound insulation descriptors.…”

Translation between existing and proposed harmonized airborne sound insulation descriptors: A statistical approach based on in-situ measurements

et al. 2017

A standard defining a common acoustic classification scheme for dwellings is under development by ISO TC42/SC2/WG29 based on the outcomes of European project COST Action TU0901. The proposal stands on the assumption that in the long term many countries will establish building acoustic requirements using a harmonized set of descriptors. In this scenario most countries will need to estimate the influence on their current airborne sound insulation requirements due to the new descriptor. This paper investigates a statistical method to obtain translation equations between existing and proposed descriptors, based on the analysis of a significant set of in-situ measurements. Several translation equations are proposed, and the effect of the building system such as heavy and light weight walls. Results show that, although it is possible to propose a single translation equation for each existent descriptor, in some cases the spread around the proposed translation line is significant. Overall, the effect of building system is more noticeable if different frequency range descriptors are involved in the translation. For some existent descriptors, the obtained translation is compared with the theoretical method proposed within the findings of COST TU0901. When considering only lightweight walls or the full data set, there is no good agr eement between both methods, but for heavyweight walls they converge. Existing requirements in most European countries have been translated into the proposed descriptor DnT,50 ≈ DnT,w + C50-3150 using the obtained equations. This provides valuable information and an insight for government and building regulation policy makers when updating their legislation.
