Daily exposure
84.0dB(A) LEP,d
Equivalent 8-hour daily exposure.
Exposure share
25.0% of 8h
Duration compared with an 8-hour day.
Explanation
What this calculates
The calculation normalises the measured or estimated level to an 8-hour working day.
Formula
LEP,d = noise level + 10 x log10(hours / 8)
Inputs are validated on screen and converted where unit options are available.
Worked Example
Example result
90 dB(A) for 2 hours is approximately 84 dB(A) LEP,d.
