Acoustic insulation materials to meet these characteristics
2021.03.12
When we renovate a house, we choose some sound insulation foam materials that can be soundproof. Sound insulation is the isolation, partition and separation of sound or noise through certain objects, so we need sound insulation cotton material to meet these characteristics.
1. Soft and high tensile strength
Soundproof cotton material is soft and high tensile strength, especially suitable for home use, and also can isolate certain noise effect, which is the choice of house decoration.
2. Environmental protection and health
These sound insulation wool materials have passed the relevant certification of the environmental protection department and are protected to meet the requirements according to different environments, and this material will not cause environmental pollution.
3. This material is light and thin
In the premise of noise reduction, the higher the density of the noise reduction material, the better the sound insulation effect and the better the internal pores of the material. So the light and thin sound insulation cotton is more suitable for sound insulation.
4. Inhibit the propagation of low frequency sound waves
Sound insulation cotton material uses metal powder, which has a strong inhibiting effect on the propagation of low-frequency sound waves, thus reducing the range of indoor noise propagation.
5. Various ways of use
Soundproofing wool can be used alone or on top of other panels to give full play to its performance. When used in combination, static and acoustic mats play a positive role in the sound insulation performance of resonant panels.
In recent years, various functional nonwoven fabrics have been developed and applied. There has been a great breakthrough in sound insulation materials. Compared with inorganic fiber sound-absorbing materials, it is light in weight, small in size, and easy to transport and install.
