Abstract
A portable acoustic absorber system which can be used in particular in open office environments or in large spaces with unwanted echoes or excessive noise. The device operates by supporting and arraying panels of efficient sound absorbing materials in a helical configuration in which a majority of the surface area of those panels is exposed. During shipping, or when the device is not in use, it can be reconfigured into a closed position, which occupies much less space.
