✦ Synopsis

A method of predicting sound pressure levels from an explosive source has been developed by the author to assist in the control of artillery firing at Larkhill.

Measurements have shown that, for a given charge weight and source to receiver distance, changing meteorological conditions can alter the observed sound intensities by over 30dB.

The method is valid for a wide range of weather conditions and will model observed sound foci including those upwind. The RMS error in the predictions is less than 6dB for levels of lOOdB or more (peak linear).

Application to other types of sound source and corrections for topography are under development.
