Types and variations of sound absorbing materials
Noisy or echoing rooms are certainly uncomfortable because they interfere with the auditory system. Indoor noise pollution can even break the focus and cause stress, especially when noise is generated in workspaces that require high concentrations from the user. Sound absorbing material is the best material to reduce indoor noise.
Silencers not only reduce noise, but also reduce the speed of sound so that the room is not too quiet. The sound absorbing material can control the sound in the room until it reaches the ideal noise level of 55dBA.
Material construction principles
As a rule, silencers work by applying an acoustic system to the room. Sound itself is the principle of sound arrangement that stores and absorbs sound in an enclosed room. This material helps block noise that affects one room to another.
By installing a sound absorbing material, the sound generated indoors can be heard more naturally and clearly. Not surprisingly, this material is often used in music studios and cinemas to produce higher sound quality.
Types of silencers
There are three types of silencers that can create a sound room with good sound quality. The three types are made of special materials that have different indoor sound processing and control functions.
The first is a silencer that absorbs sound energy so that the sound does not bounce back into the room. This principle is also known as echo timing control (Reverberation time).
Some silencers control the movement of sound between two rooms by returning the sound reflections back to the room from which the sound originated. Finally, there is a sound damper whose job is to control the vibration effect of the sound that causes vibration in the building structure of the room.
Various sound absorbing materials
At a minimum, silencers have six material choices. Each has its own features and benefits. Now, take a full look at the following!
1. PET material
There are various types of materials that can be used as sound absorbing materials, such as cloth, plaster, egg foam, and polyester. Rock wool,and Soft board. However, polyethylene terephthalate (PET) is the most commonly used material by major manufacturers because it can absorb and absorb sound at the same time.
In addition, PET is highly malleable, so it can be easily adapted to the size and shape of the room. Installation of this silencer is also very practical as it does not require a frame.PET mounting on walls, floors and ceilings can be done with nails, yellow glue, or Double-sided tape..
The soundproof color of PET is quite diverse, so it is very flexible to match the interior design of the room you are carrying. Regarding the risk of PET chemicals, this material is made from recycled plastic, so it is more environmentally friendly.
2.2. glass wool
Well then there is the sound absorbing material glass wool. This type is a material made from basic materials Fiberglass..For textures, fleece and wool.. The thickness of the material itself is about 2.5 cm to 5 cm and the density or density is about 25 g / cm³ to 75 g / cm³.You can find the material glass wool It is on the market in the form of rolls in the range of 30 meters in length.
3.3. Rock wool
Sound absorbing material Rock wool Made of lightweight mineral fiber that can absorb not only heat but also sound.At first glance, this material is similar to glass wool, It's just the density of the material Rock wool Higher in the range of 30g / cm³-100g / cm³.Therefore, many people use it Rock wool As the second layer of silencer glass wool.. If you are interested in this material, you can buy it in sheets or rolls.
4.4. Green wool
silencer Green wool It is a material made of material polyester fiber Waterproof or Hydrophobic It is not easily affected by humidity.In fact, the material for this green silencer was born out of consideration for that material. Glass wool and rock wool Not good for your health.Yes, thanks to the basic ingredients of the foam polyester, Then the material greenwoool It is considered safer and less dangerous.
For installation, this material can be pasted or planted on the surface of the wall.Kania's suggestion, you use better Green wool Up to 2 layers to minimize noise.
5. Egg foam
You may already be familiar with this very popular and commonly used soundproofing material. The egg foam material is fairly lightweight and easy to apply. However, this material is not optimal enough to reduce high frequency sounds. Alternatively, the follicle material can be used as an additional layer of soundproofing.
6.6. Soft board
In addition, there is a fiber sound absorbing material polyester..Its thickness ranges from 1.2 cm and is generally Soft board Brown like a tree. You can use this one material to attenuate the echo and absorb the extra room sound.Installation is a normal material Soft board Wrapped in cloth or wallpaper silencer.
7. Natural sound absorbing material
In addition to using various materials, it is also possible to arrange sound absorbing materials in the room by using sound absorbing ornaments and objects. Carpets that cover the entire floor of a room and books that fill the walls can be used as natural sound absorbers.
Regardless of the type of sound suppressor used, natural or artificial, the level of air reduction factor can be adjusted as needed. This material can be flexibly placed on the walls, floors and ceilings of rooms.
The amount of noise cancellation you place in the room to avoid noise depends on your space requirements. If you attach a sound insulation material to the silencer, the sound quality in the room will be better. Interested in installing sound absorbing material in your room?
