Our Services
We provide FREE house to house & Site Sound level (Decibel) measurement services.
Where there is a noise problem, You have to evaluate two facts:
- Determine or measure the external noise level
- Decide the desired noise inside the room
Recommended Noise Level
| Bedroom | 30 – 35 dB |
| Public Library | 40 – 45 dB |
| Urban Neighborhood | 50 – 55 dB |
| Industrial Area | 60 – 70 dB |
| Busy Street | 70 – 80 dB |
By subtracting the common indoor noise level from the Outdoor noise level YOU can estimate the appropriate acoustic performance you need for your windows.
For example:
External noise source 71 dB
Requested room noise level 35 dB
Difference = 36 dB
* in our advise, a 36 dB rating is required for the window system.*
