| * +3dB(A) Façade effect correction included |
|
|
|
| #
- Limit Level of 70dB(A) applies to education institutes while 65dB(A)
applies during school examination period. |
|
|
| **
Construction noise level is only calculated when Measured noise level (Leq)
> Baseline noise level. |
|
|
| If Measured noise level < Baseline
noise level, Corrected noise level = Measured noise level |
