GYC Sound Absorption Agent
GYC sound absorption agent is designed to be applied on the traditional physical sound absorption material by adding the agent into the coating or into the material itself to improve the sound absorption effect and reduce the noise levels. The sound absorption agent can be applied to squares surrounded by buildings, wall paints, curtains, and so forth.
Description
Intro
In general, people use the material itself to absorb the noise, in other words by using physical way to achieve the sound absorption effect, such as cork woods, foamed plastics, sponges, mineral wools that are with a large number of pores. When the air passing through those pores, the friction will cause the acoustic energy to be depleted. However, while the sound absorption material is not sturdy but frail, the sound will easily go through the material and the sound absorption effect will be largely reduced.

Principle
When the noise passes through the sound absorption material, the noise will firstly go through the surface layer that the sound absorption agent has been added into its coating. Next it will pass through the inner layer into which the sound absorption agent is added
Advantages
- Improve or provide the materials with the ability of absorbing sound waves
- Effectively absorb the noise and reduce the noise levels
- Reduce echo
- Applied to any material surface
- Can be used with noise barrier and building insulation/absorption materials
- Can be used with other functional additives (e.g. flame retardant) to add more value to the end-product
Applications
- Used in the sound absorption structure of wall bodies or indoor ceilings
- PU synthetic leathers
- PU/PVC foams
- Construction noise barriers, high way
- Concert halls, theaters, conference rooms, broadcasting studios, factory buildings
- Textiles, curtains
- Other sound absorption applications
dB Measurement
Add GYC sound absorption agent into automotive interiors and test the decibel levels
| Dosage | Average dB level |
| 0 % | 74.41 dB |
| 6-9 % | 58.33 dB |
Dosage
Recommended dosage: 3~10%
The dosage level is to be regarded as general guideline which can be adjusted according to the materials and the expected effect.
