The formula to calculate the Noise Exposure Level (NE) is:
\[ NE = L + 10 \log_{10}(T) \]
Where:
Noise exposure is a measure of the sound level an individual is exposed to over a period of time, taking into account both the volume (intensity) of the noise and the duration of the exposure. It is used to assess the risk of hearing damage or loss. The Health and Safety Executive (HSE) provides guidelines and regulations to help protect workers from the harmful effects of excessive noise.
Let's assume the following values:
Using the formula to calculate the Noise Exposure Level (NE):
\[ NE = L + 10 \log_{10}(T) = 85 + 10 \log_{10}(4) ≈ 85 + 6.02 = 91.02 \text{ dB} \]
The Noise Exposure Level (NE) is approximately 91.02 dB.
