Indoor sound insulation method of university dormitory
Sound insulation and noise reduction need the cooperation of architectural acoustics and building walls: for indoor sound insulation, it is nothing more than solving the sealing problem, and since sealing must start from many aspects, we should also pay attention to ventilation while sealing. It should be said that indoor sound insulation should be a systematic project, and the choice of doors and windows is only a part of it. It is reported that the sound insulation capacity of professional sound insulation windows ranges from 30 decibels to 40 decibels, which can generally solve the problem of noise pollution. For different sound insulation and noise reduction, it is necessary to cooperate with architectural acoustics and building walls, and it is impossible to solve the problem only by sound insulation windows.
What are the sound insulation materials?
1, sound insulation board home sound insulation decoration materials
The use of sound insulation boards in indoor sound insulation wall materials is also different in different locations indoors. Any material has a certain sound insulation effect, but we call it a sound insulation board with high processing density and good sound insulation effect. When choosing the sound insulation board, be sure to check whether there is any relevant test report. If there is no relevant report, the sound insulation effect of the sound insulation board is far from perfect.
Household sound insulation decorative materials. deadening felt
Sound insulation felt is a good indoor sound insulation material on the market at present, which is mainly used to insulate the wall and ceiling with gypsum board. It is also suitable for sound insulation and damping vibration reduction of pipelines and mechanical equipment. But the sound insulation felt is not a felt, and it is completely different from the appearance. The felt is light and soft, and the soundproof felt is thin but heavy.
Household sound insulation decorative materials 3, sound-absorbing cotton
Sound-absorbing cotton is a common material for indoor sound insulation walls, which is widely used in noisy public places such as KTV karaoke bars, dance halls, cinemas and recording studios. In addition, the sound-absorbing cotton is obviously easy to process in the decoration process, and at the same time, the sound-absorbing cotton can be moistureproof, waterproof and breathable than other decoration materials. However, sound-absorbing cotton also has its shortcomings, that is, the flame retardancy of sound-absorbing cotton is not very good, so if you choose this sound-insulating material, you should pay attention to the use of fire.
Household sound insulation decorative materials. Polyester fiber sound-absorbing board
This is also an ideal indoor sound insulation material. Its raw material is 100% polyester fiber, which has the advantages of sound absorption, environmental protection, flame retardancy, mildew resistance, good stability and good impact resistance. It has a variety of colors to choose from, which can meet the sound absorption and decoration needs of different styles and levels. Mainly used in: homes, cinemas, concert halls, galleries, studios, KTV rooms and bars.
Compared with private houses, school dormitories are not so private and sound-proof, so I also briefly introduced the indoor sound-proof methods of university dormitories to you. The population is large and the rooms are dense, so the noise has a great impact. From the above, we all know what sound insulation materials are available, and these materials can play a very good sound insulation effect.
