Noise Performance
Environ Enclosure products are designed with noise reduction performance in mind. Our acoustic engineers have developed a unique range of Environmental Enclosures that are not only compatible with virtually all makes and model of outdoor AC equipment - but designed specifically to eliminate noise altogether and improve our environment.

Noise Data
Our Enclosure Systems have been designed to achieve the highest possible noise attenuation characteristics across a wide frequency spectrum. The table below provides Insertion Loss performance common to all of our Environmental Enclosure Equipment.
| ENVIRON ENCLOSURE SYSTEMS | |||||||
|---|---|---|---|---|---|---|---|
| Octave Frequency in Hertz (dB Ref 2 x 10-5 Pascal's) | |||||||
| 63 | 125 | 250 | 500 | 1k | 2k | 4k | 8k |
| 12 | 13 | 20 | 29 | 36 | 37 | 39 | 39 |
