Abstract

Identifying and perceptually characterizing the physical properties of rooms is a fundamental step in understanding the acoustical qualities of a space. Over the last century, numerous studies have investigated the perceptual qualities in performance spaces, such as opera houses and concert halls. In smaller spaces, such as domestic environments, the research focus has been primarily steered toward sound reproduction within a room, rather than the transmission medium, the room. In this study, a new methodology is used to perceptually assess and characterize a range of acoustical properties within small rooms and car cabins. In-situ measurements were performed to obtain a range of possible acoustical settings, by varying physically the spaces under investigation. The measured responses were spatiallyanalyzed and synthesized to reproduce the observed fields in the laboratory. Expert listeners were presented with auralized sound over a loudspeaker array and followed a rapid sensory analysis protocol. The elicited attributes and ratings are analyzed and possible links to the acoustical properties of these spaces are discussed.
