- The problem of noise in dwellings is topic of large discussions nowadays. Not only airborne noise but also impact noise are responsible for decreased comfort of living. The subjective evaluation of impact noise sounds in dwellings are described in this paper. Listening tests based on method of adjustment (1) with statistically sufficient sample of tested subjects were performed in a listening test room in the laboratory of TGM where subjects compared the performance of acoustically presented floors. Impact noise stimuli were measured as the sound coming through various floor constructions with similar Ln,w values, sorted into three main groups: (i) masonry concrete structure, (ii) cross laminated timber (CLT) structure and (iii) light-weight timber structure. Comparisons of listening test performance with calculated single number quantities for each construction were prepared in order to understand the perception of presented sounds by dwellers. The results from this preliminary study are meant as a basis for adjusting of currently applied reference curve also with particular focus on the low frequency range.
