How does the choice of the sound reproduction system affect the perceptual evaluation of impact sound insulation?

In listening test design, the choice of the sound reproduction system is often one of the least regarded issues and is guided dominantly by convenience, availability, or financial constraints. The influence of this choice on the results of listening tests specific for room and building acoustics has been made the topic of broader research. This paper presents the preliminary results of the study made within this framework on a listening test based on loudness matching, designed for subjective evaluation of impact sound insulation. The listening configurations considered in the study are: mono signal from four overhead speakers and a subwoofer ; a 2nd order Ambisonics system ; mono signal on uncalibrated headphones ; mono signal on calibrated headphones with a flat frequency response ; mono signal on a hybrid system using headphones and a subwoofer ; a binaural Ambisonics system. The listening test is performed on all configurations and the differences in the obtained results are discussed.
