TYPES OF SOUND SILENCER MATERIAL
Hello friends of Bali Interio, in addition to the sound produced, the sound also maintains the speed of sound so as not to make the room feel too quiet. The silencer is able to control the sound in the room to find the ideal level, which is 55 dBA.
| Material Working Principle |
In principle, sound works by applying an acoustic system in the room. Acoustics itself is the principle of sound arrangement that precipitates and absorbs sound in a closed room. This material comes from originating from one room that affects other rooms.
By installing sound, the sound produced in the room will sound more natural and clear. Not surprisingly, this material is applied to music studios and cinemas to produce higher sound quality.
| Type of Acoustic Material |
Polyethylene Terephthalate (PET) is the material most often used by major manufacturers because of its ability to absorb and absorb sound at the same time. In addition, PET is also very easy to shape so it is easy to adjust to the size and shape of the room. This sound installation is very practical because it does not require a frame. Installation of PET on the surface of walls, floors, and ceilings can be done directly by using adhesive tools such as nails, yellow glue, or double-sided tape.
The appearance of the sound color of PET is quite varied, very flexible to match the interior design of the room used. Regarding the dangers of the chemical content in PET, this material is made from recycled plastic so it is more environmentally friendly.
This type is a material made of fiberglass. For the texture, it is similar to fleece or wool. The thickness of the material itself is about 2.5 cm – 5 cm with a density or density of about 25 g/cm³ to 75 g/cm³. You can find glasswool material on the market in the form of rolls with a length range of 30 meters.
Rockwool is made of lightweight mineral fibers that can absorb sound and heat. At first glance this material is similar to glasswool, only the density of rockwool material is higher with a range of 30 g/cm³ – 100 g/cm³. Therefore, many use rockwool as a second layer of glasswool silencer. If you want to be interested in this material, you can make sheets or rolls.
Greenwool is a material made of polyester fiber with water resistance or hydrophobic properties so that it is difficult to affect air humidity. Actually, this green sound material from the beginning considered that glasswool and rockwool materials were not good for health. Yes, thanks to the basic material in the form of polyester, green wool is considered safer and less dangerous.
For installation, this material can be affixed or planted on the surface of the wall. Kania advises, you should use two layers of greenwool so that noise can be muffled to the maximum.
Egg foam material has a fairly light weight and is easy to apply. However, this material is not optimal enough to be considered high-frequency sound. As an alternative, you can use egg foam material as an additional soundproofing layer.
Softboard is a material made of sound made of polyester fiber. Its thickness is around 1.2 cm and generally the softboard is brown like the color of wood. You can use this material to be considered an echo and absorb excessive sound. For installation, softboard material is usually wrapped with cloth or wallpaper that is not noisy.
In addition to using various materials, sound regulation in the room can also be done by utilizing ornaments and objects that have the ability to absorb sound. Carpets that cover the entire floor of the room and books that fill the walls can be used as natural sounds.
Soundproofing in hardwood or tile requires underlayment and subfloor to reduce your transmission.
Gypsum Board Material
As a room divider, gypsum material has many advantages, starting to be resistant to fire, resistant to earthquake shocks, and making the room cool faster. Not only that, gypsum can also be a soundproofing in the room because it has an acoustic function. The acoustic function of gypsum includes two things, namely soundproofing and sound absorption.
