The aim of this study is to explore acoustic comfort in family apartments in Scandinavia, not only regarding standardized acoustic data but also including the users’ perception of their living sound environment. A first approach takes place for the definition of the concept of acoustic comfort, which was rarely defined before and used to be mostly interpreted as absence, low, or acceptable levels of noise in a place. In this article, acoustic comfort is not only lack of discomfort, it is explained as the ability to have proper sound conditions in overall, for a certain activity in a certain space, considering physical characteristics and the users' demands. Then, a method is set up for the evaluation of comfort in dwellings, including acoustic measurements and social surveys in test buildings. A questionnaire for the collection of the subjective responses of the tenants, regarding noise annoyance, sound perception, and emotions, is presented and analyzed.
