Used to control harsh reflections, reduce reverberation time, or eliminate echo. Absorption panels can also be used to reduce the propagation of sound in otherwise open areas (i.e., down a long hallway).

Sound Isolation can be defined as the degree of acoustical separation between two locations, especially adjacent rooms. When dealing with sound isolation you must consider that only two things stop sound - mass and space. You need mass to contain the airborne sound, and you need space (an air gap or similar unobstructed area) so that the structure borne sound cannot be transmitted.

Structural born noise is often the hardest to deal with. You need a high mass and an air space as mentioned above so that there is no positive structural contact. For example, in the case of a hard floor above the listening environment you would need to decouple the floor joists from the ceiling joists. The most common and effective way to do this is to use resilient sound Isolation clip.
