Calculate Daily Noise Exposure — Free LEP,d Calculator for UK Employers
Estimate your workers' daily noise exposure (LEP,d) from multiple sources and see which UK regulatory action values apply.
Important: this calculator estimates unprotected daily average exposure (LEP,d) only.
It does not account for peak sound pressure (LCpeak), weekly averaging (LEP,w), or the noise reduction provided by hearing protection. The 87 dB(A) exposure limit value depends on protected exposure, which this tool cannot assess. Use this as a screening estimate — not as a substitute for a competent noise assessment.
Noise sources
Add each noise source your worker is exposed to during a typical working day.
