Noise pollution in modern urban settings poses a substantial threat, far exceeding a basic annoyance as it undermines the overall wellness and standard of living experienced by those residing in metropolitan areas. Traditional mitigation strategies have often been narrowly focused on the reduction of noise levels. However, this perspective misses a crucial aspect: the broader need to design urban spaces that provide enriching and positive acoustic experiences. This article delves deeply into the intricate dimensions of soundscapes within urban contexts. Through a comprehensive exploration of varied global case studies, we showcase innovative urban design interventions that effectively balance noise control with the enhancement of the broader auditory environment. These interventions encompass a wide array of strategies, from the incorporation of natural elements such as parks and water features, which contribute both visual beauty and auditory calm, to the utilization of advanced sound-absorbing materials and architectural techniques. Furthermore, we highlight the emerging trend of creating designated quiet zones within bustling city centers, providing residents with pockets of tranquility amidst urban chaos. Through a comprehensive analysis and aggregation of the available evidence, our study strongly highlights the indispensable necessity for city architects, lawmakers, and builders to adopt a more encompassing and cooperative method regarding acoustic planning within urban environments. Such an approach should not only prioritize noise reduction but also recognize and amplify the potential of sound as a foundational and enriching component of urban life. Through this, cities can evolve into spaces that minimize auditory disturbances and actively enhance the well-being of their residents by providing positive acoustic experiences.

“…Only more recently have researchers started looking at a broader range of sound sources that are more likely to be experienced in everyday life, how similar acoustic environments combinations are to one another, and how these aspects contribute to noise annoyance formation (e.g., [ 19 , 20 , 21 ]). Along with developments in the definition of environmental sound source taxonomies [ 22 , 23 , 24 ], these studies have demonstrated the impact of the semantic meaning of sound sources on the affective perception of the soundscape. However, they have not yet explored how different combinations of sound sources (e.g., bird song AND water sounds AND traffic noise) can explain the perceptual impact differently than considering the sources individually.…”

Noise annoyance has been often reported as one of the main adverse effects of noise exposure on human health, and there is consensus that it relates to several factors going beyond the mere energy content of the signal. Research has historically focused on a limited set of sound sources (e.g., transport and industrial noise); only more recently is attention being given to more holistic aspects of urban acoustic environments and the role they play in the noise annoyance perceptual construct. This is the main approach promoted in soundscape studies, looking at both wanted and unwanted sounds. In this study, three specific aspects were investigated, namely: (1) the effect of different sound sources combinations, (2) the number of sound sources present in the soundscape, and (3) the presence of individual sound source, on noise annoyance perception. For this purpose, a large-scale online experiment was carried out with 1.2k+ participants, using 2.8k+ audio recordings of complex urban acoustic environments to investigate how they would influence the perceived noise annoyance. Results showed that: (1) the combinations of different sound sources were not important, compared, instead, to the number of sound sources identified in the soundscape recording (regardless of sound sources type); (2) the annoyance ratings expressed a minimum when any two clearly distinguishable sound sources were present in a given urban soundscape; and (3) the presence (either in isolation or combination) of traffic-related sound sources increases noise annoyance, while the presence (either in isolation or combination) of nature-related sound sources decreases noise annoyance.
