“…Thus, they have been rejected from the analysis. If water sound sources are active factors when one focuses on specific locations such as parks or open squares [40], [41], this effect can probably be neglected when considering very contrasted sound environment at a district scale. …”

Mapping the pleasantness of an urban environment is an alternative approach, closer to the city dweller's perception, than standardized sound levels cartography. This study reports on modeling pleasantness in urban context using perceptual assessments and sound measurements for specific locations during an urban walk. These assessments have been collected from four groups of approximately ten participants on 19 different assessment locations, along a 2,1 km-long path traveled in both directions. Simultaneously, ⅓ octave band sound levels and audio were recorded. Perceptual and physical models of pleasantness are proposed for specific locations based on multiple linear regressions. A multilevel analysis was performed, and it is shown that a perceptual model that includes perceived loudness joined to the perceived time of presence of traffic, voices and birds explains 90% of the pleasantness variance due to the sound environment variations. Physical models that include the original acoustic indicators that are most correlated with perceptual variables explain 85% of this variance. Thanks to these models, a unique averaged pleasantness value is defined for each assessment location from the perceptual or physical collected assessments. The Pearson's correlation coefficient between the averaged perceived pleasantness and the modeled values from perceptual assessment reaches r(19)=0.98, and r(19)=0.97, with the modeled values from physical measurements. These results make it possible to consider the use of this kind of models in a cartographic context. As the path was traveled in both directions, the presentation-order effect has also been assessed, and it has been found that path direction did not have a significant impact on the pleasantness assessment at specific locations, except when very strong sound environment changes occurred. Finally, the study gives some insights about the retrospective global pleasantness assessment for urban walks. For very short walks between two assessment locations, a recency effect is shown. Nevertheless, this effect doesn't seem to be significant when longer routes are assessed.

“…Among researchers there is also no clear consensus yet regarding the soundscape terminology and choices of bipolar adjectives [19,20,[23][24][25][26]. In particular, the issues arise in the selection criteria for bipolar adjectives used, which is accompanied by the question of universal applicability due to loss of certain semantic nuances in translation and determining proper statistical approach.…”

“…There are also other studies that have shown that people especially enjoy the sound of water 6 . In that sense, we can conclude that the real challenge is how to create an enjoyable soundscape in nowadays overpopulated cities.…”

“…So far soundscape research has been oriented mainly on evaluating a soundscape in a qualitative way, e.g. assessing the soundscape pleasantness or rather its unpleasantness [6]- [9]. In order to describe a certain soundscape in greater detail and provide a more comprehensive approach to soundscape research, it is necessary to use other methods which could also define soundscape characteristics quantitatively.…”
