PREFORATED ACOUSTIC PANELS
The perforated acoustic panel allows a high degree of sound absorption. There are different types of perforated acoustic panels which can be used as walls or ceiling. They complement the interiors and the finish of the panels can be customised accordingly.
In the perforated acoustic panels the perforations help in sound absorption together with the core material and the air space. The perforated acoustic panels are also available with slots instead of perforations which is as effective for sound attenuation and mitigation.
The panels provide a high degree of thermal insulation. The internal core material could vary from fibre glass to foam. The perforated acoustic panels are fire resistant and non-combustible. They are very durable and resistant to wear and tear and adverse weather conditions.
The Perforated panels are an economical way to get sound control. We have some standard size perforated panels readily available we can also manufacture other sizes as per the requirement.
| Test Cavity | Center Frequency (HZ) | 125 | 250 | 500 | 1000 | 2000 | 4000 |
| 5cm cavity | Sound absorption coefficient | 0.23 | 0.46 | 0399 | 1.04 | 0.89 | 0.82 |
| 10cm cavity | Sound absorption coefficient | 0.37 | 0.72 | 0.87 | 1.02 | 1.12 | 0.91 |
| 20cm cavity | Sound absorption coefficient | 0.43 | 0.94 | 0.85 | 1.11 | 1.13 | 082 |
PREFORATED METAL ACOUSTIC PANELS
The perforated metal panels have an outer casing made of galvanised steel or aluminium. These panels are filled with fibre glass which is compressed in a poly vinyl bag for optimal acoustic control.
Perforated metal acoustic panels are usually used for industrial application. They are very effective for controlling noise reverberation and eliminating sound echo.
Features of perforated metal panels :
- Highly durable
- Abuse resistant
- Fire resistant (class B)
- Insulated
- Weather proof
- Corrosion resistant
These perforated metal acoustic panels can be used on the ceiling or as wall panels. It is an ideal solution for demanding environments where the sound levels are difficult to contain. The panels have an attractive appearance and it adds to the aesthetics of the areas.
Some areas of application
- Power Plant
- Waste water treatment plant
- Noisy environments
