Abstract
Acoustic comfort in dwellings is often underprioritized and appears to have worsened as modern interiors favor hard surfaces. This project investigates how to classify acoustic indoor comfort in contemporary homes. The study reviewed current standards and regulations and examined how well standardized room-acoustic parameters describe perceived sound. To collect objective data, a measurement program was developed and room impulse responses were recorded in accordance with ISO 3382-2 across 45 rooms in 15 dwellings. In parallel, a questionnaire captured residents’ subjective ratings, yielding 15 responses. The dataset was analyzed using multiple factor analysis to link objective measures and subjective perceptions. Findings indicate substantial redundancies among standardized parameters and show that room absorption correlates more strongly with acoustic satisfaction than reverberation time, a relationship not reflected in existing standards. A larger database is required to establish a robust classification of acoustic comfort.
Akustisk komfort i boliger er ofte underprioriteret og synes at være forringet, i takt med at moderne indretning favoriserer hårde overflader. Dette projekt undersøger, hvordan akustisk komfort kan klassificeres i moderne boliger. Der blev gennemgået gældende standarder og regulativer og analyseret, hvor godt standardiserede rumakustiske parametre beskriver oplevet lyd. For at indsamle objektive data blev der udviklet et måleprogram, og impulssvar blev målt i overensstemmelse med ISO 3382-2 i 45 rum fordelt på 15 boliger. Parallelt blev et spørgeskema anvendt til at indsamle beboernes subjektive vurderinger, hvilket gav 15 besvarelser. Data blev analyseret med multiple faktor-analyse for at sammenholde objektive mål og subjektive oplevelser. Resultaterne peger på betydelige redundanser mellem de standardiserede parametre og viser, at absorption i rummet korrelerer stærkere med akustisk tilfredshed end efterklangstid, hvilket ikke afspejles i nuværende standarder. En større database er nødvendig for at etablere en robust klassifikation af akustisk komfort.
