Acoustics and soundproofing is basically the physics of sound and concerns the quality of sound and how to reduce noise in a building or auditorium. The science behind acoustic auditorium works on reducing echoes and noise within the hall so as to increase the quality of sound. The Acoustics are also concerned with noise and disturbances coming from the outside of the building. Those who are still new to the science of acoustics, might have many questions rising in their mind such as how does acoustic treatment work and how is it used in buildings and to suppress outside noises?

Acoustics cover the complete production and transmission of sound within the building.Whenever looking after auditorium acoustics design or in work places, office, or cinema theatres etc, there are certain aspects that need to be focused on. An important point of consideration should be that the quality of sound received in any part of the hall should be sufficiently loud and clear. There should be no changes or alterations of the sound quality in any corner of the room or hall. One should not find any vibrations due to resonance and there should be no noise disturbances coming from the outside. Acoustic panels and acoustical foams are chosen according to the location and requirement of the room. For example, an office located right by the side of busy and noisy street will require more effort in getting acoustic treatment.
Perhaps you have listened to speakers kept outside. The sound becomes thin and dull and this is what exactly happens to the reflected sound within an enclosed room. The reflected sound turns bad in quality when some of the reflected notes amplify while cancelling out others. This leads to bad acoustics and distorted sounds. The overall tonal quality of the sound gets disturbed and leads to an echo-like effect. One will come across three kinds of reflected sounds such as absorption, pure reflection and diffusion.
Whenever picking acoustic auditorium wall panels or for any buildings, certain factors should be kept in mind such as echo and reverberation for complete soundproofing home theater. Those excessive reflections of sound are caused by echoes in the room and can severely distort the quality of sound. These echoes are common in an enclosed room. While a true echo is a single reflection of sound from the main source, it is not uncommon to come across several echoes within a room. Reverberation occurs when the sound remains even after the removal of the original sound. This occurs when one gets a large number of echoes to build up in an enclosed space. The walls and air gradually absorb the sound till it decays and decreases in amplitude. The sound source has stopped but those reflections continue. Special attention needs to be paid to acoustic auditorium where there are more chances of multiple reflections of sound.
To get a perfect auditorium acoustics design, you need to focus on these aspects and pick the right acoustic auditorium wall panels and acoustic foam to get the ideal quality of sound within the auditorium or building.
