11 Manual method of measuring shot noise

If a manual method is used, the LZpeak hold level that may be reasonably attributed to an audible shot must be recorded and—

(a) if the difference between the level of the shot and the peak hold level immediately preceding the sound of the shot is at least 3dB—the noise level must be classified as Category A, or

(b) if the difference is between 0dB and 3dB—the noise level must be classified as Category B, or

(c) if there is no difference—the noise level must be classified as Not valid.
