How to Distinguish Acoustic Materials?
In the modern living environment, sound-absorbing material always plays a vital role, whether it is the decoration of the studio, or the conference room in the commercial decoration, sound-absorbing material always play a small role. For example, if there is a music lovers at home, who will bother the neighbors and his families when the guitar is played. At this time if we decorate his room with sound-absorbing material, it can play a very good role. Of course, the sound-absorbing material is much more than that. For example, sound-absorbing materials never lack of the application in the opera house, conference room, studio, or cinema. How to distinguish whether the sound insulation material is good or bad? If you have this demand, you can follow me to understand the next sound-absorbing material prices and related knowledge.
Sound absorbing material types:
Sound-absorbing materials are generally divided into three types: fiber type, foam type and granular type.
The acoustic panels commonly on the market are wood acoustic panels, fabric acoustic panels, polyester fiber acoustic panels, wood wool acoustic panels, etc.
Fiber-based materials are divided into two types: organic and inorganic fibers. Organic fiber is mainly sound insulation cotton, slag cotton, glass fiber, rock wool and so on, among which the glass can be made of glass felt. Sound insulation cotton is the most commonly used sound-absorbing material, its advantage is non-combustible, heat-resistant, corrosion-resistant and so on. The soundproof cotton also can play a fire, moisture effect after being treated by the silicone oil.
Foam-type material has the advantages of small bulk density, thermal conductivity, soft texture and the disadvantage is easy aging, poor fire resistance.
Granular type of material can be moisture proof, insulation, corrosion and so on.
Which sound absorbing material is better?
Thick carpet: the best choice for ground noise reduction
Today, home treatment for ground is probably marble, tiles or wooden floor. In order to reduce the sound reflected from the floor, we need to cover a moving thick carpet on the ground between the speaker and listening location. If you just want to use a small piece of thin carpet, it will only has the decoration effect but no real sound-absorbing effect.
Wood acoustic panels: the best choice for wall noise reduction
Wood sound-absorbing panels are made of wood materials, and added a layer of sound-absorbing material on its surface, the surface restores the wood principle, which is simple and natural, embodies the modern rhythm of the bright and beautiful style and has woody aroma. Wood acoustic panels have strong decoration performance, which are manufactured in line with national standards.
Fabric acoustic panels: the best choice for indoor sound-absorbing
The indoor sound insulation material fabric acoustic panel uses centrifugal glass wool which has a strong sound-absorbing effect recognized worldwide, and this material is widely used in sound-absorbing materials industry. It has a strong sound absorption, sound insulation effect, more durable, lighter quality, mildew proof and moisture proof, and a variety of colors available, decorative effect is very nice.
How to distinguish sound absorbing material?
Step One: Of course, feel by hands. Generally good sound-absorbing materials feel soft and fluffy. Because good sound-absorbing material generally use fine fiber, which will be naturally fluffy. Therefore, the same volume sound-absorbing material will naturally be more light, more conducive for the sound waves entering and being absorbed. And ordinary blanket material is too heavy and not fluffy.
Step Two: Squeeze the material by hands. Good quality sound-absorbing material has high rebound rate, which can effectively rebound to maintain its fluffy state even if suffering from short squeeze. Some shoddy sound-absorbing materials on the market seem fluffy early, but they will not be enough fluffy after squeezing. The key is that the resilience is poor.
Step Three: Smell with the nose. Sound-absorbing material used in the car firstly should be non-toxic and no taste, keep the air quality fresh. Good sound-absorbing material has no taste, and will has no smell distributing even in the summer when it is very high temperature in the car, which belongs to healthy and safe materials.
