A sound rated flooring is provided comprising a sound attenuation layer having a composite panel structure having a core and at least one acoustically semi-transparent facing of fibrous material bonded to the core and a rigid layer positioned on the sound attenuation layer. A moisture inhibiting barrier may be positioned between the composite panel structure and the rigid layer. A method for constructing a sound rated floor is also provided, comprising the steps of positioning the composite panel structure described herein over a substantially horizontal base surface and then positioning the rigid layer over the composite panel structure. The finished covering is then placed over the rigid layer.
