| Summary: | This article addresses the topic of environmental comfort from a salutogenic and pedagogical point of view. It begins by presenting a wide framework aimed at describing the complexity and specificity of the acoustic issue and the need to integrate decibel-based metrics with knowledge and reflections which are inherent to non-measurable factors. The article then focuses its attention on educational spaces and presents the results of an investigation carried out in 52 classrooms of 19 primary schools in Florence. From this research and keeping in mind the current Italian legislation, the following results are deduced: (1) the layout of a typical classroom, (2) the average reverberation time and (3) the sound-absorbing surface required to improve the acoustic quality of the typical classroom with polystyrene fibre panels. Subsequently, after having briefly described the more appropriate typology of sound-absorbing solutions, a system for the acoustic correction of classrooms is presented. This system is composed of two parts. The first part is fixed and its realisation is entrusted to specialised personnel; the second, based on the concept of personalisation and transformation of the educational space, is modifiable through time and designed and applied by the students themselves.
