The sound is often reflected before reaching the listener from all directions. There are several possible ways of thinking, each individual reflection is very close in time to their neighbors, so there is a dense set of reflections that reach the listener. This part of the sound in the theater is called reverberation is desirable, as it adds richness, and supports, musical sounds.
Reverberation in the theaters at home also helps to incorporate all the sounds of an instrument for a listener to hear a sound that incorporates all the sounds of instruments, including the steering parts. Indeed, we have found home theater facilities in spaces that have very little reverberant, uncomfortable and generally not suitable for listening to music.
The time required for a reverberation occurs depending on the size of the home theater room and will be shorter for smaller spaces due to the shorter time between reflections and losses in each impact with a surface. In fact the time interval between the direct sound and the reverberation in the dedicated home theater is important for the size of the piece being played the soundtrack signal. Due to the sound is absorbed with each reflection on the acoustic panels the film ends up dying away. The time it takes to clear the sound is called reverberation time and depends on both the size of the home theater room and the amount of sound absorbed at each reflection.
In fact, there are three aspects of the effects of the home theater reverberant room field:
1. Increasing the reverberant field level of cinema:
This is the first part of the reverberant field and is affected by the size of the home theater room, which affects the time between reflections and thus the time it takes to accumulate the reverberant field. The amount of absorption in the home theater room also affects the time it takes the sound to reach its level of steady state. In other words, the speed at which sound is collected in a dedicated home theater depends on the time between reflections and absorption time. This simply means that the reverberant sound level will take longer to reach more than a smaller home theater room.
2. The stable level of reverberant field of the Home Cinema:
If a home theater system plays a continuous tone, after a period of time the reverberated sound will reach a constant level because at that time the input sound power balances the power lost by absorption due to acoustic wall panels. This means that the level of steady state will be higher in home theaters that have a small amount of sound absorption panels, compared to movie theaters that have a lot of absorption treatments.
3. The decline in the reverberant field of the cinema:
When the tone in the home theater stops, the reverberated sound level does not immediately reduce but disintegrates at a rate determined by the amount of sound energy that is absorbed at each reflection with acoustic panels and other surfaces. Thus, in the home theater facilities with a small amount of absorption of the reverberant field will take longer to disintegrate.
