Perceptual evaluation of differences between original and synthesised musical instrument sounds: the role of room acoustics

International audienceTo better understand the properties of musical instruments, their recordings in controlled situations are often compared with computational models that recreate such situations. The purpose of this study was to apply psychoacoustic descriptors to measured and modelled signals of a musical instrument and to identify whether there were perceptual dierences in the signals. The hummer was chosen, which is a musical instrument that generates sound when it is rotated at certain speeds, due to airow exciting the resonance frequencies of the system. In a previous study, we found perceptual dierences for loudness uctuations and roughness for an evaluation in anechoic conditions. In this study, we have applied similar evaluation criteria to audio signals that account for the rst reections coming from one room surface. Perceptual dierences were found in the perceived pitch when adding the reected sounds into the computational model. For one rotation condition, dierences in loudness were also found
