Shake it slow the floor low frequency noise how to do? Sanya, Haikou bar insulation board damping pad wholesale November 22, 2012 15:12:09 Bar Soundproofed decoration including wall ceiling soundproof floor sound insulation, windows and doors, sound insulation, piping sound insulation - Part 4! O speeding, China's first professional ktv soundproof overall service providers, and integration services to provide sound insulation design, materials, construction, EIA-stop! shake it slow ktv_ Bar _ the Noise perfect solution, to provide ktv_ Bar _ shaking it slowly soundproof materials and professional ktv_ of Bar _ slow roll soundproof construction. shake it slow ktv_ Bar _ the soundproof renovated look for Macau speeding the (China highest integrity ktv_ of Bar _ slow roll noise company) more "slow roll flooring how to do low-frequency noise? Sanya, Haikou bar insulation board damping pad wholesale" information preferred Macau speeding! Ventilation soundproof windows reduce sound transmission device coupled with the unique structure is a partition attached absorb the sound of steel or aluminum extrusions. It includes two window frames, quite, and the inner and outer glass windows installed in between the window frame and in quite. Have ventilation and sound insulation window professional research institutions and enterprises and institutions: Architecture, Tsinghua University, Physical Acoustics Laboratory, race Lee acoustical engineering. Practice of ventilation and sound insulation window to make a significant effect, be a strong response in the market, many people named custom installation, creating a harmonious society a lot of money benefits. Lightweight wall insulation measures several of the following: (1) multilayer dense sheet of porous materials (such as glass wool, rock wool, foam, etc.) separated, made into a sandwich structure, sound insulation than materials weight the same as the single-layer wall can improve a lot. (2) to avoid plate anastomosis critical frequency falls within the range of 100-2500Hz. 25mm thick gypsum board fc is about 1250Hz, divided into two layers of 12mm thick SLAB, fc is approximately 2600 Hz. 60mm thick, hole plate, consistent with the critical frequency 600Hz is mainly audio area, resonant sound transmission combined with a central circular hole, making poor sound insulation performance, not as good as the weight of the same thickness is reduced solid plate. (3) If the wall of the light sheet made of separate double wall, because of the material stiffness, the surrounding steel the sound bridge connected impact, therefore, the same structure as the double wall of an additional sound insulation than high. If the layer of air between filled with long and short material, sound insulation performance can be further improved. If both sides of the double wall of wallboard with different thickness, allows each anastomosis Valley staggered. (4) light panels are often fixed on the keel plate and keel sword pad elastic cushion (such as elastic sheet metal, elastic material pads) than the sheet directly given larger amount of sound insulation in the keel. (5) the use of double-layer or multi-layer sheet superimposed and compared to the same weight of a single layer thick plate, on the one hand, consistent with the critical frequency can be moved to the main audio range, on the other hand multilayer staggered joint stack set to avoid board crevice deal with bad sound leakage, but also because of the friction between the laminated layer enables improved sound insulation than a single plate. In short, the measures to improve the insulation of light wall, nothing more than the multi-layer composite, double wall discrete sheet laminated, flexible connection, plus fill in the sound-absorbing material, increasing the structural damping. Through appropriate structural measures, it is possible to make some light sound reduction wall to reach the level of 240mm brick wall, with good sound insulation effect. ③ in Figure 12-25 for each side of the double-layer 12mm plasterboard, light steel keel, filled with glass wool, light walls, the amount of airborne sound insulation Rw fairly with 240mm brick wall, while the latter weighs only 1 / 10 slow roll flooring how to do low-frequency noise?
