Abstract To improve the impact sound insulation performance of building floors and meet the objective requirements for
living comfort of residents, in this article, three kinds of elastic cushion materials, Portuguese cork board, BGL
insulation sound insulation foam board, and EPP polypropylene plastic foam board, are applied to the sound
insulation of a light frame wood floor structure of the same bedroom and compared to the ordinary floor. This
study uses the transfer function method and transient excitation method to measure the sound insulation, damping ratio, and elastic modulus of materials, as well as the sound insulation of the floor under… More >
