About: Noise Prediction Calculator

The equation for this calculation is as follows:

         Distance = 215(NEQ)1/3

Noise Prediction Calculator

This calculator can be used to predict the distance from a detonation at which 140 decibels (dB) could be expected to be achieved. The 140dB level is widely used as a "safety cutoff" for exposure to impulsive noises while using hearing protection.
