Reverberant field dominates home hi-fi listening from just 2 meters away
Evidence
Clearly the level of the reverberant field is strongly affected by the level of average absorption. The first example would be typical of an extremely βdeadβ acoustic environment, as found in some studios, whereas the second is typical of an average living room. β David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1776 (

If a steady tone, such as an organ note, is played in the space then after a period of time the reverberant sound will reach a constant level because at that point the sound power input balances the power lost by absorption in the space. This means that the steady-state level will be higher in rooms that have a small amount of absorption, compared with rooms that have a lot of absorption. β David Howard, Jamie Angus, coustics and Psychoacoustics, 1781 (
