Noise pollution on the human body is actually a great harm, so we then need to understand the noise reduction and sound insulation materials, so what are the noise reduction and sound insulation materials? Here I will introduce you to the noise reduction and sound insulation materials.
Noise-reducing and sound-absorbing materials generally have three major types of fibers, foams and particles.
Fiber class is mainly divided into inorganic fibers and organic fibers, inorganic fibers are mainly acoustic cotton, glass wire, slag wool, rock wool and its products.
Particle sound-absorbing materials commonly used can be roughly divided into perlite sound-absorbing products and ceramic particles sound-absorbing products; based on the shape of the sound-absorbing products can be subdivided into sound-absorbing panels and sound-absorbing bricks.
Noise-reducing sound-absorbing materials of polyester fiber acoustic panels, a product with efficient sound-absorbing properties, but also cotton sound-absorbing materials. The invention and promotion of polyester fiber acoustic panels is a success for the entire acoustic industry.
Noise-reducing sound-absorbing materials of wood acoustic panels, a kind of sound-absorbing materials made of wood, with highly efficient sound-absorbing properties, non-toxic, environmentally friendly basic features, is a rare trend of new products in the home decoration industry.
Noise-reducing sound-absorbing materials grooved wood acoustic panels,
compared to other perforated acoustic panels, grooved wood acoustic panels is a straight line grooved way to achieve the sound-absorbing properties, which is the most distinctive of all acoustic panel products.Noise-reducing sound-absorbing materials of sound-absorbing cotton, a sponge sound-absorbing products, its comprehensive performance is in the middle of the lower position, the performance is not very outstanding.
In addition, polyester fiber sound-absorbing panels and metal sound-absorbing perforated panels are also very good noise-reducing sound-absorbing materials.
1, polyester fiber acoustic panels
Polyester fiber acoustic panels are new imported materials, made of 100% polyester fibers, can be very good at absorbing noise and preventing strong reflection of indoor sound and affect the indoor environment.
2, metal sound-absorbing perforated plate
Metal sound-absorbing perforated plate is a metal coil in accordance with a certain aperture and density of perforation, and then pressed into a variety of shapes of the metal material, mainly used for the noise requirements of the place of the roof bottom plate. In crowded places, micro-perforated ceiling with sound absorption can eliminate noise and reverberation.
Noise pollution will not only make our ears feel uncomfortable, more seriously, noise pollution is actually a great danger to people's health, we should pay attention.
