Facade Sound Insulation as Protection to Outdoor Noise
* Presenting author
In recent years the acoustic qualification of buildings has gained more and more importance at international level. One of the important elements for determining the sound quality of houses is the insulation against external noise. In fact, many issues related to excessive noise in dwellings arise from their inclusion in noisy environments, or from their original surrounding environment, which has grown from silent to very noisy over the years.The main strategy to limit the noise inside the buildings is the façade insulation improvement. Regulatory requirements and classification schemes in Europe present a high degree of diversity. In particular, the approach to the façade insulation acoustic requirement adopted in the various countries is very diversified also because closely related to the external noise climate. The main issues related to the façade sound insulation are investigated with particular regard to the choice of descriptors, to the evaluation methods and their reproducibility, which is the less easy to evaluate.
