Sustainability and acoustics: what are we looking for?

摘要

Sustainability has introduced new dimensions in building design. To start with, there is a recognized wish for better acoustical quality at the workplace and also in one's dwelling, which translates into more and more stringent acoustical targets. Unfortunately, the higher the targets does not always mean the better the feeling of the inhabitants or users! More to the point, thermal and visual aspects often prompt the builders to use materials or techniques that are often not in the best interests of acoustics! This means that first of all a sound discussion must be carried out between all members of the design team as well as with the end user. Decisions will have to be taken on the basis of a vigilant diagnosis of both premises (if existing) and working / living habits that will be carried out prior to any attempt at dimensioning a new project. This paper will discuss the diagnosis and target definition steps through a couple of case studies.
