Sound Quality Evaluation for the Workplace: Research on the Influence of Spatial Sound Distributions
This study reports on some practical experiments with subjective hearing in simulated workplace situations. A methodological approach for sound quality evaluation is developed. Here two experiments are described which investigate the influence of room geometry and absorber placement
on the perception of loudness, roughness and sharpness under conditions where the room volume, the sound level, and the reverberation time were kept constant. The results presented in this paper directly describe simulated (virtual) situations and relate perceptions to objective quality parameters
respectively calculated on a mathematical model. The deviations across different signals are small, both for the subjective and the objective results, but they are in line, showing this approach worth of trying.
