Acoustics is the science concerned with the production, control, transmission, reception, and effects of sound. It has widely spread in various industries, including automotive, speakers, microphones, concert hall and other places.
We have the ability and experience to supply the acoustic products for your projects and production:
Nowadays, there are two major speaker grilles at the market: micro expanded metal (stretched metal meshes) and perforated metal meshes. The micro expanded metal is slit and expanded rather than punched, there is no waste material during production. This can save up to 50% material and costs for users and make the micro expanded metal a cost effective alternative to perforated metal in acoustic attenuation and speaker grilles.
| Item | Thickness (mm) | Strand Width (mm) | SWD (mm) | LWD (mm) | Width (mm) |
|---|---|---|---|---|---|
| YSGM-01 | 0.5 | 0.5 | 1.5 | 2.5 | 150–500 |
| YSGM-02 | 0.5 | 0.5 | 1.7 | 2.8 | 150–500 |
| YSGM-03 | 0.5 | 0.5 | 2.1 | 3.0 | 150–600 |
| YSGM-04 | 0.5 | 0.5 | 3.0 | 4.5 | 150–600 |
In downtown area and heavy traffic area, the noise troubles civilians long term. There are several noise barrier products at the markets, such as perforated metal or louver type noise barriers. But they all need the extra sound absorbing materials to achieve the needed effects and some of the sound absorbing material is not environmentally friendly.
As we all know the sound resistance of surface material is inversely proportional to the open area. Thinner opening, better sound resistance. So, we recommend the micro expanded metal as the noise barrier.
The noise barrier is evenly distributed with raised pyramid and oval tiny holes. When the noise contact with the surface of noise barrier, most of the noise are reflected and attenuated by the raised pyramid. And the rest noise/sound are penetrated through numerous tiny holes and long passing distance. At last, most of the noise/sound are reduced. Thus, it can achieve better noise reduction and sound absorption performance and it is more environmentally friendly.
