“…The previous conclusions from studies [3][4][5][6][8][9][10][11][12] are contradictory to the general trend in impact sound measurements and descriptors: inclusion of low-frequency spectra down to 50 Hz (even down to 20-25 Hz) in impact sound data is considered necessary to achieve sufficient association with self-reported responses. [27][28][29][30][31][32][33][34][35] However, sometimes the same is stated in studies for airborne sound: in Park and Bradley, 11 many associations were very good between subjective annoyance or loudness and SRI descriptors for various stimuli with low-frequency content too. In addition, in Hongisto et al, 12 descriptors such as R w and STC with extended frequency range down to 50 Hz are suggested perform best for prediction of subjective annoyance and loudness to music stimuli (but not the other sounds tested).…”

“…When it comes to vertical sound transmission, most studies deal with impact sound data as a priority, which is critical for propagation through floors and it has been found to be the most disturbing noise type in residential buildings. 14,[27][28][29][30][31][32][33][34][35] Therefore, it seems that airborne sound studies remain supplementary to impact sound for researching vertical noise transmission.…”

“…The other papers found were excluded because they concerned impact sound laboratory studies [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] or field studies. [31][32][33][34][35][36][37][38][39][40] Other exclusion criteria were the year of publication and language: only articles published after 1980 in English were included. The bibliographic research took place between April 2015 and September 2017.…”

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 low coefficient of determination obtained by the D nT,w (walls) and D 2m,nT,w was expected. 15,16,35 The higher correlation coefficient obtained for the D nT,w (slabs) and ′ L nT w , may suggest that in concrete slabs, the users' annoyance regarding noise from this type of partition is more noticeable than in the others. In fact, the correlation shows a clear perception of the users regarding this annoyance, which demonstrates a fragile point in the criteria established by the norm in relation to the acoustic comfort coming from this structural element.…”

Rating of acoustic performance levels of NBR 15575 (2013) based on user perception: A case study in the Brazilian Amazon

The new Brazilian building performance standard is a landmark in terms of housing regulation in Brazil. Nevertheless, due to the standard recent release, it becomes essential to make its requirements compatible with users' needs. This work has the objective to evaluate the acoustic performance requirements of buildings based on the users' perceptions of acoustic comfort. In order to do this, field tests were performed and surveys were applied to the users. The results demonstrate that the requirements defined by the Brazilian norm are unsuitable to meet the users' necessities. The correlation analysed shows a clear perception of the habitants in relation to the transmitted noise through the slabs and walls. These unsatisfactory results concern the acoustic performance of impact noise between slabs, as well as internal and external walls, showing that construction companies must implement new solutions that can provide greater acoustic performance to achieve acoustic comfort to the users.

“…L , and the only difference is the test site. It is worth noting that Sweden has taken into account the spectrum adaptation term and a Swedish scholar[8] studied the necessity of using it. It was found that the spectrum adaptation term is suitable for the light or semi-light structures, such as lightweight timber structures.…”

At present, the impact sound insulation performance of the residential floor attracts increasing attention, which is a critical index to evaluate the physical performance of the residential building. Improving the sound insulation performance is an effective measure to improve the living quality and solve the contradictions between neighbors. Therefore, many sound insulation standards have been established to guide the design of building sound insulation. In this paper, comparisons between Chinese code and Eurocode on the impact sound insulation requirements of the residential floor were presented, including the evaluation parameter and the limit value of sound insulation. In addition, the applicability of limit value of sound insulation standard for each country was analyzed in detail through the existing experimental data of different floor structures, and then reasonable suggestions were put forward.
