“…A gender effect was reported for the perception of the music stimulus, depending on sound level, in the laboratory study by Yang and Moon [19]: At 55 dBA women reported greater acoustic comfort than men, while at 75 dBA the opposite was observed. In another laboratory study on the perceptual assessment of combined indoor water sounds and environmental noise, Yang et al reported women rating isolated water sounds as more pleasant, while no gender effect was observed in judging environmental noise in isolation [24]. When combined, compared to men, women were found to perceive water sounds as having a greater effect on annoyance, pleasantness and noisiness.…”

“…Factors associated to the physical character of the acoustic environment affect in different ways the dimensions underlying its perception by building users. Noise annoyance ratings were reported to be positively related to sound levels [15][16][17][18][22][23][24][25][26]28,32,35,37,41,43,45,46,48,49,51] and negatively related to the source distance [32,42,43]. Acoustic comfort was also related to sound level [19].…”

“…Yang et al tested in their laboratory experiment whether exposure to short-term indoor water sounds could enhance the perception of traffic noise transmitted through ventilation openings [24]. Exposure conditions were obtained by combining indoor water sound levels (35.8-59.8 dBA) with levels of environmental (i.e., road traffic or railway) noises (43.0-62.1 dBA) that had been recorded next to windows in the living rooms of actual residences.…”

Assessment Methods and Factors Determining Positive Indoor Soundscapes in Residential Buildings: A Systematic Review

et al. 2019

The design of an indoor acoustic environment positively perceived by building occupants requires a perceptual approach to be adopted in order to define what makes it sound good. Soundscape standards ISO 12913 have been introduced to assess how the acoustic environment is perceived, in context, by people. According to the standards, a straightforward characterization of a soundscape as positive is currently possible only through measurements by persons, because of a current gap in linking perceptual metrics to acoustic or psychoacoustic measurements. In addition, despite applying also to indoor contexts, methods and perceptual metrics described by the standards have been mainly derived from studies related to outdoor urban environments and it is not clear whether they could be directly applied indoor. For this reason, a systematic review was performed to investigate: (i) Data collection methods used in the literature for indoor residential soundscapes and (ii) factors, output of such methods, that characterize them positively. For this purpose, a systematic review has been conducted in accordance with the PRISMA guidelines (preferred reporting items for systematic reviews and meta-analyses) guidelines. The Scopus database was searched for peer-reviewed journal papers published in English, between 1 January 2009 and 24 June 2019, including: (1) field or laboratory studies relevant to residential buildings and (2) studies assessing factors that influence the perception by building users of indoor acoustic environments. The search excluded studies related to: (a) Speech perception issues; (b) noise-induced sleep disturbance; (c) acoustic perception by hearing impaired building users; (d) perception of vibrations or impact sounds. The search returned 1087 results. After the screening process, 37 articles were finally included. Given the differences in methodologic approaches, a quantitative meta-analysis could not be performed, and a qualitative approach was adopted instead. A large part of the selected literature reflected a general effort of minimizing noise annoyance by reducing noise exposure and, in particular, noise levels. Questionnaires and guided interviews were used to capture people’s perception, while the adoption of soundwalks and non-participatory behavioral studies did not emerge in the review literature and need further investigation. The evaluation of a variety of auditory sensations both in their positive and negative dimensions, beyond annoyance, would be required to explore the positive perceptual potential of sounds. Besides sound level, a variety of factors related and unrelated to the acoustic environment were found to affect perceptual outcomes and a framework of evaluation has been proposed as a reference for future assessments. Results encourage the integration of soundscape methodologies into IEQ research, in order to enhance user health and well-being.

“…All alternatives improve the scores of the acoustic sequences, which significantly affect noise acceptance evaluations. Moreover, a similar study on high acceptance of acoustics on evaluation was conducted in a previous research, in which the pleasantness of traffic noise -0: Scores of the acoustic units 2-Ⅲ-1: Scores of the acoustic sequence 3-Ⅲ-1: Start section replacement 3-Ⅲ-2: Middle section replacement 3-Ⅲ-3: End section replacement 3-Ⅲ-4: Three-section replacement environments increases significantly, when the occurrence of birdsong over a period of 30 s is increased43 , and water sound resulted in an improvement of environmental noise, where the perception of annoyance reduced and that of pleasantness increased44 .…”

Noise acceptance is an aspect of indoor soundscape research. While staying or walking in a transport hub, sequential sounds form sequence sounds sessions, which is referred to as an acoustic sequence. The basic phenomenon and effects of acoustic sequences on acceptance evaluations have been explored. A total of 209 sections of 30 s acoustic units were extracted before performing acceptance evaluations. The acoustic units were divided into strong, medium, and weak levels and compiled into 37 pieces of acoustic sequences, which were then subjected to four tests for acceptance evaluation: sound content, acceptance level, and effects of weak and strong acceptance units. One piece of an acoustic sequence consists of 20 acoustic units. The results show that all acoustic sequences exhibit "attenuation effects," as for any acoustic unit that make up the sequence, general acceptance decreases with time. The lower the acceptance, the faster the decay in score. High acceptance units have an "enhancement effect," and the acceptance increases after a high acceptance unit. Low acceptance units have a "boost effect," and the acceptance increases after a low-level acceptance. Both enhancement and boost effects could improve the acceptance evaluation of acoustic sequences and sound experiences in transport hubs.
