- W2012120223 abstract "In order to determine the performance of baffles in nondiffuse fields such as those found in typical industrial workrooms, reverberation times and steady-state sound-pressure levels were measured in a 1:8 scale-model workroom with variable dimensions, containing various arrays of baffles. The objective was to determine the effect of changes in various room and baffle-array parameters on the sound field as characterized by the early-decay time and the sound-propagation function. The parameters studied were fittings, room height, roof shape, baffle density, baffle pattern, baffle aspect ratio, baffle thickness, and baffle composition. The experimental results show that the changes depend on room geometry and on whether the room is empty or fitted, and that they are different for early-decay time and for sound-propagation function. The most significant results were that roof shape and baffle pattern have little effect; increased baffle density generally results in reduced early-decay time and sound-propagation level, but using too high a density is ineffective; baffle aspect ratio had a small effect; high baffles are slightly more effective than wide ones; increasing the baffle thickness resulted in slightly lower early-decay times and sound-propagation levels; nonabsorbent baffles were much less effective than absorbent ones." @default.
