Description
The acoustic classification methods for residential dwellings—and particularly the one developed in the ISO/FD 19488 Technical Specification—employ several performance indicators to characterize the acoustic quality of housing. In order to better correlate occupants' perceptions with these indicators and, ultimately, with acoustic classes, a new Documentation Fascicle (FD S30-109) establishes a methodology for conducting perception surveys.This methodology will be presented in its entirety, beginning with the acoustic parameters upon which it is founded. A detailed description of the survey’s structural framework will follow, supplemented by an outline of the various contextual and psycho-social factors to be considered. Key principles and best practices will be discussed, along with recommendations for correlating survey results with acoustic measurements. Finally, selected excerpts from a sample questionnaire will be presented and analyzed.
