This Nordtest prediction method specifies calculation of noise in the vicinity of shooting ranges, etc. from single shots fired with small arms. Formulas are given for calculations in 1/1- octave bands. It is based on the Nordic general prediction method for industrial noise, /2/, and on the reference noise level, which describes the noise emission from the weapon. A measurement method for determination of the reference noise level of muzzle noise is included as Appendix C.
