This paper outlines the main content of the Rayleigh Medal Lecture, which reviews the author's work in the last 40 years, with a transformation from sound propagation focused to sound perception focused, along with the demanding from the society, to create a quieter, safer, more comfortable and sustainable sound environment.The paper includes three main sections:1) The work since 1983, focusing on sound propagation, namely the physical aspect of sound in our built environment, both indoor and outdoor.2) The soundscape work in the last 20 years, along with the practical demanding of creating quiet areas required by the EU Directive [1].3) The current work on the development of Soundscape Indices (SSID), based on an ongoing European Research Council (ERC) Advanced Grant project.While this paper is relatively brief, more detailed information can be found from the video-recorded version of the lecture.

“…However, Devos [112] questions the use of soundecology indicators in areas where anthropogenic sources are dominant, and indicates that the reliability of these indicators is associated with the measurement duration, as well as other acoustic indicators, due to the variability of the analyzed sound sources. Xiang et al [113] show that soundscape diversity indices are more suitable than soundecology indicators for assessing sound diversity in green spaces.…”

Purpose of Review Urban green spaces provide benefits for human health and well-being, among other properties, thanks to their ability to attenuate environmental pollutants. The sound environment is not healthy in most cities, and this situation has not changed in recent decades. These green spaces are potential quiet areas with good acoustic quality if they are designed and planned properly from a multidisciplinary perspective. Although the mitigating effects of green infrastructure have been extensively studied, their application in green areas has been very limited. The objective of this study is to analyze those characteristics of green spaces that contribute to a healthy soundscape and, in turn, the benefits that this would give them to the characteristics of green areas, users, and their physical environment. Recent Findings Current studies show that to accurately determine the relationship between green spaces and health and well-being benefits, it is necessary to know the interaction with other environmental variables, including the soundscape. The development and application of ISO/TS 12913-2 have promoted the consideration of the soundscape and the use of appropriate procedures for its evaluation. Summary The inclusion of soundscape quality in epidemiological studies will improve the quantification of the effects of green spaces on the health and well-being of citizens. Only the consideration of global indicators, such as Lden (dB), show the importance of the sound environment in the interaction with other environmental variables and user activities for the determination of the effects of green spaces on health.
