If you want to install room acoustics and do not know much about it, then it can be quite a daunting task for you initially. There are a lot of options available with acoustical panels that make it difficult for you to choose one. Firstly, you should know the exact frequency of sound you wish to control and absorb. Then you need to know which room or rooms you want to soundproof. You can also look for 3d acoustic panels via http://www.modulararts.com/auralscapes/wallpanels.html.

Mostly, people need to adjust and absorb mid-level to high-level sound frequencies. For example, in a newsroom, where the majority of the sound that bounces in the room is the human voice. To absorb this sound, you will need to install acoustical panels. In case, you need to control low bass frequencies, you will need to install bass traps as well. The best examples, in this case, are recording studios and home theaters.
A very important aspect to take into consideration is the fire rating of the panel. Generally, you should avoid purchasing acoustic panels that are manufactured with inflammable material. It is very dangerous to hang such kind of inflammable material around your walls. A lot of manufacturers also offer to treat the fabric topically by covering it with chemicals. These chemicals are specially made to support the fabric against fire.
Having your fabric treated with this type of chemical means that if the fabric catches fire, it will self-extinguish against fire. However, topically treated fabric loses its resistance against fire with the passage of time. The flame resistance of these acoustic panels should sustain for longer because they will not be washed. But many people suggest that it is better to install intrinsically flame retardant fabric since safety against fire is extremely important.
