“…Descriptions of soundscapes need not only the acoustical numbers, but also semantic data [18] which can be presented as key factors, principal components or perceptual dimensions (these names all mean the same thing and can be used interchangeably). These perceptual dimensions of a soundscape can form a kind of "evaluation structure" [22], on which people can assess soundscapes. Therefore, for studies which focus on the study of "positive" soundscapes, it is important to consider the other multiple dimensions on which soundscapes can be evaluated.…”

“…On the other hand, the concept of soundscape involves the perception of the acoustic environment. Different models of subjective evaluation have thus been proposed in the literature with significant perceptual attributes being established, such as eventfulness, the pleasure experienced by the listener, and the sound activity, to name a few [22][23][24][25][26]. The influence of other stimuli (primarily visual) in the perception of sound have also been the aim of some studies [27][28][29].…”

Assessing soundscape: Comparison between in situ and laboratory methodologies

Abstract:The assessment of soundscape implies an interdisciplinary approach, where objective and subjective aspects are considered. For the subjective evaluation, in situ and laboratory methodologies are usually followed. Local observations allow the collection of information on the influence of different stimuli present in the environment, whereas laboratory tests present a determined quantity of controlled stimuli to the evaluator. The purpose of this work is to compare results from the different methodologies in order to understand their strengths and their weaknesses. Three urban parks in the city of Lisbon, Portugal, were evaluated. Fragments of binaural sound recordings collected in the parks were used in laboratory tests to compare with the responses in situ and of expert and nonexpert listeners. Statistically significant differences were found in several of the perceptual attributes under observation, which led to variation in the results of the main model's components. The sound environments were found to be more pleasant and uneventful in situ than in the laboratory, a phenomenon possibly due to the influence of other stimuli such as visual in the process of assessment. The in situ tests allow a systemic and holistic evaluation of the environment under study, whereas the laboratory tests allow a specific and tightly targeted analysis of different component sound events. Therefore, the two methodologies can be useful in soundscape assessment depending on the specific application and needs. No differences were found in the assessment made by either experts or nonexperts.

“…[30] Through a factor analysis process, the semantic scales could be divided into several groups which indicated the major perceptual factors of soundscape perception. Earlier studies focused on individual sounds [26,27] and then expanded to environmental sounds. Four essential factors were found in residential areas: adverse, reposing, affective and expressionless [28].…”

“…By laboratory experiments, two or three main factors were extracted [17,18,27], whereas more factors were identified in studies that use field surveys [28,32]. These results revealed that there were unavoidable differences between recordings and real urban soundscapes.…”

This paper aims to find a series of objective indicators that can fully describe the soundscapes of urban shopping streets. The perceptual and physical features of soundscapes in urban shopping streets have been investigated via field surveys and a laboratory study. Using the semantic differential method, the perception structure of shopping street soundscapes was initially analysed, and five major perceptual factors were identified that explained 64% of the total sample variance, including preference, loudness, communication, playfulness and richness. Each perceptual factor explained approximately 10% to 15% of the total variance, which showed that they shared very similar importance in the representation of the overall soundscapes in urban shopping streets. Based on this semantic differential analysis, a laboratory study was performed to investigate the relationship between perceptual factors and physical indicators. Sound levels and psychoacoustic indicators were initially considered to be the most common indicators. The results showed that there were significant correlations between these indicators and three perceptual factors, including preference, loudness and communication. A new indicator (dynamic spectrum centre or DSC) was then developed in this study based on the concepts of spectrum gravity centre analysis and temporal variety analysis. This indicator combined spectral and temporal analysis to describe the contents of background sounds and sound events. The DSC indicator was found to have a significant correlation with the other two perceptual factors (playfulness and richness). Increasing the variability of the sound event (a higher standard deviation of DSC_E) could make soundscape more playful and richer.Yu et al: Acta Acustica united with Acustica
