This open access book highlights the negative and positive health effects of chronic exposure to environmental sound. It describes the state of the art in the field from a public health point of view and puts it in a broad societal perspective looking at sound from physical, social, psychological, economic and governance angles. Rather than a mere collection of papers around the theme as usually provided in special issues, this book offers a comprehensive look at the meaning of sound in society and its impacts and provides directions to further advance the field.
