Abstract
Methods and apparatuses for reducing the transmission of unwanted sound and vibration energy generated by dynamic and/or impact loads through floors in multi-story buildings. This may be accomplished using an acoustic wave transformation and attenuation sound proofing membrane including an acoustic wave transformation layer, an acoustic absorption layer, and a constrained vibration damping layer. The acoustic wave transformation layer may be capable of transforming acoustic waves in a manner that may easily be attenuated by the acoustic absorption and constrained vibration damping layers. The sound proofing membrane may be used with several different combinations of floor coverings, adhesives, and subfloors. Impact acoustical tests have demonstrated that the sound proofing membrane can achieve higher IIC and HIIC ratings compared to conventional acoustic underlayments and/or membranes and, thus, prevent unwanted dynamic and/or impact loads from disturbing occupants in rooms beneath the floor assembly.
