Background technique
Solid sound that is to say decaying very little of the energy of strike note in traditional building material, and spread speed ratio is in air
Fastly, propagation distance is again far, and the air-borne sound sound insulation effect of existing concrete floor is good, but for the effect of strike note (solid sound)
But very, therefore the resident that stays in lower layer generally can't hear the voice of upper layer resident, but upper layer resident drag desk, child run jump, shoes
Sound with tapping ground influences lower layer resident very big.It, can be in slab in concrete structure for the sound insulation property for improving floor
Upper laying carpet is laid with elastic surface layer material, drags part caused by the activities such as desk, race jump to hit to absorb upper layer resident
Hit energy, weaken or prevent the vibration of floor, thus achieve the effect that improve floor sound insulation, but be laid with elastic fabric or
Carpet not only increases a part of cost, and carpet using constant, many residents do not like using carpet simultaneously, and for happiness
For the people on joyous tile floor and all kinds of floors, elastic surface or carpet are also inconvenient for use.
For the sound insulation effect for improving floor bottom plate, some sound insulating materials are generally set in floor bottom plate, are compared in the world
" floating to build method acoustical insulation floor " approved combines the method as elastic insert using professional sound insulating pad and extruded sheet, and floor is hit
12dB can be reduced by hitting sound oise insulation factor.Not only strike note sound insulation effect has and is obviously improved above-mentioned technology, while also functioning to heat preservation and making
