10 Classification of shot noise

(1) The noise level from a shot must be classified as one of the following—

(a) Category A,

(b) Category B,

(c) Category C,

(d) Category D,

(e) Not valid.

(2) The noise level of a shot must be classified as Category A if the noise level—

(a) has a peak level higher than the peak level immediately before the sound of the shot, and

(b) cannot be attributed to another extraneous noise or due to weather conditions.

(3) A Category A level is considered an accurate representation of the noise contribution from the shot.

(4) The noise level of a shot must be classified as Category B if the noise level has a peak level that may have been elevated by the weather or extraneous noise.

(5) A Category B level is considered as an upper estimate of the measured noise from the shot unless it is clearly affected by extraneous noise in which case the noise level must be classified as Not valid.

(6) The noise level of a shot must be classified as Category C if the shot is audible at the measurement location but the noise level from the shot cannot be classified as Category A or Category B.

(7) A Category C level is not considered a measurable noise contribution from the shot.

(8) The noise level of a shot must be classified as Category D if the shot is not audible at the measurement location and the noise level from the shot cannot be classified as Category A or Category B.

(9) A Category D level is not considered a measurable noise contribution from the shot.

(10) The noise level of a shot must be classified as Not valid if, in the opinion of the person making the measurement—

(a) the noise level is the result of a noise that is not shooting noise, or

(b) the noise level is the result of shooting noise that is not shooting noise from the range being measured, or
