Room reverberation barely affects early reflection audibility but strongly elevates late-reflection thresholds
Evidence
The large changes in the level of reflected sound had only a modest (1 to 5 dB) effect on the absolute threshold or the image-shift threshold of an additional lateral reflection occurring within about 30 ms of the direct sound. At longer delays the thresholds were elevated by up to about 20 dB, a clear response to stronger late-reflected sounds in the increasingly live rooms. — Toole, Floyd E, Sound reproduction- the acoustics and…, 630
