Tommy Dowd early on installed variable acoustic sound traps that affected both the low frequency absorption and the reverberation time in the studio.
32.
If the reflection is coherent, the reverberation time of the hall will be longer; the sound will take more time to die out.
33.
After determining the best dimensions of the room, using the modal density criteria, the next step is to find the correct reverberation time.
34.
The optimum reverberation time for a space in which music is played depends on the type of music that is to be played in the space.
35.
The new reverberation time, 1 . 8 seconds ( up from 1 . 6 ) matches that of Carnegie Hall and of Symphony Hall in Boston.
36.
Ambient noise levels and reverberation times were considered ideal but the occupant satisfaction ratings for now were average to poor and were generally worse than benchmarks.
37.
In 1965, Manfred R . Schroeder published " A new method of Measuring Reverberation Time " in the " Journal of the Acoustical Society of America ".
38.
Basic factors that affect a room's reverberation time include the size and shape of the enclosure as well as the materials used in the construction of the room.
39.
Where critical distance d _ c is measured in meters, volume V is measured in m? and reverberation time RT _ { 60 } is measured in seconds.
40.
The total absorption in sabins ( and hence reverberation time ) generally changes depending on frequency ( which is defined by the acoustic properties of the space ).
