Room acoustics is the broad term that describes how sound waves interact with a room. Each room, and all the objects in it, will react differently to different frequencies of sound. Every speaker will sound different in different rooms. In simple words, room acoustics means sound proofing of an area. But it is not that straight forward. While keeping in mind the requirement of sound proofing in an area, it is also important to ensure that the acoustics do not off balance the ambiance of the room. Hence not only the selection of material to be used for sound proofing is important but its also important to keep in mind the interior design of the room as to make the room look more appealing. The sound proofing levels are taken care of in terms of percentages with different materials for different percentages. Though it is not necessary to include it with home theaters but its a not to miss feature that one should add to the home theater room so as to get the exact ambiance as a commercial theater.
