An 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 MC 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.

The present invention relates to a dehumidification bag and a preparation method thereof. The dehumidification bag comprises a bag body including a first side sheet and a second side sheet, the side sheet comprises an air-permeability and/or a composite film, wherein at least all or part of at least one side sheet is an air-permeability film; a moisture-proof layer covers the outside of the air-permeability. The dehumidification bag provided by the present invention provides an air-permeability on the bag body, and adopts heat sealing between the outer surface of the air-permeability layer and the moisture-proof layer, so that the air-permeability and the moisture-proof layer are in close contact without moisture absorption, which effectively prevents damage during transportation and storage. In the process, the air-permeability is in contact with the air in the outer bag and the effect of the dehumidifier becomes poor or invalid; by setting the moisture-proof layer to be tearable, when the buyer uses the dehumidification bag, the moisture-proof layer can be torn off, which is convenient and fast.
