Possible representative indoor acoustic environment spectra

Résumé

The goal of this investigation is to evaluate the possibility of defining an alternative indoor sound spectrum based on objective and verifiable data, representative for an average household in Europe. Such an alternative indoor sound spectrum could then be used to evaluate airborne sound transmission performance. Different noise subcategories of commonly found sound sources in residential buildings are proposed, and a corresponding representative noise spectrum is given for each noise category. The effect of considering time filtering (Slow and Fast) in the analysis of the sound source time signals and in the determination of the maximum noise spectrum is investigated. Then, alternative indoor sound spectra are obtained based on the emission spectra of the considered sound sources subcategories, each being weighted by its estimated occurrence time. The comparison of the different alternative indoor spectra obtained is discussed. Furthermore, three main sound sources categories are also investigated.
