Huali Rock Wool Sound Absorption And Noise Reduction Performance

   Noise cause trouble to people's work and life

 Today is March 3, 2022, which is the 23rd National Ear Care Day. The theme of this year is "Caring for Hearing Health, Listening for a wonderful Future".Hearing health is closely related to the happiness of our life, and kinds of noise in our life bring trouble to our work and life, and even cause hearing damage and mental diseases. The problem of noise has aroused people's great concern.

    It is important for hearing health to keep the comfortable acoustic environment in our living life. Now More and more construction projects choose sound-absorbing materials to reduce noise. Huali rock wool as an excellent fire insulation material, its sound absorption and noise reduction performance is also excellent, can comprehensively improve the fire safety, energy saving and carbon reduction and acoustic comfort of buildings.

The principle of sound energy conversion

    The sound energy inside a building travels through a complex process as it passes through obstacles, and its energy is lost each time it is reflected and passed through air or acoustic materials.

    In the above case, the sound is reflected through the sound absorbing material, the stone wall, and absorbed by the air and two other different materials, both of which dissipate the energy of the sound wave and reduce the noise.

Sound absorption material

    Understanding the principle of energy conversion in sound transmission can help us to choose suitable sound absorbing materials. The most commonly used sound absorbing material is the fibrous material with chorionic villus. Because "the sound causes the vibration of fifibers, waves penetrate the structure of material, result in sound decreases gradually.

    Compared with closed cell material, products with open cell are effective sound absorbers.For example, this kind of polystyrene or XPS material, sound can not penetrate into the material, so this kind of closed cell product has a poor sound absorption effect.

Huali rock wool

Huali has the 27 years of manufacturing and construction experience in the filed of insulation materials, our products also have excellent sound absorption and noise reduction performance.and huali fifibrous rock wool material allows sound to penetrate into the internal structure, to achieve the function of sound absorption and noise reduction.
