Simply put, how does the brain process the distance of a source of sound?
Does it rely on the physical difference of arrival times between the direct wave and the reflected waves or does it interpret the comb filtering effects as they sum and process the perceived difference? Could we fool the brain with homogeneous absorption across a given bandwidth? Lets say an absorption coefficient of .5, which translate to 6dB. For every doubling of distance we lose 6dB, so having a panel with an absorption coefficient of .5 behind the speaker could effectively double the perceived distance or halve the required distance from the wall.
Just curious
