13 Determining noise levels from shooting ranges—manual method

(1) If more than 50 Category A shots are measured within 1 hour of commencing the measurements—

(a) the noise level for the shooting range is the arithmetic average of the first 50 Category A shots, and

(b) the determination of the noise level may be regarded as representing a true measurement since there is no interference.

(2) If 50 Category A shots are measured within 1 hour of commencing the measurements—

(a) the noise level for the shooting range is the arithmetic average of the 50 Category A shots, and

(b) the determination of the noise level may be regarded as representing a true measurement since there is no interference.

(3) If fewer than 50 Category A shots but 30 or more Category A and B shots combined are measured within 1 hour of commencing the measurements, the noise level for the shooting range is the arithmetic average of the total number of Category A shots and Category B shots.

(4) If fewer than 30 Category A shots and Category B shots combined have been measured within 1 hour of commencing the measurements—

(a) the measurements may be continued until the numbers in subsection (1), (2) or (3) are reached, or

(b) the measurements must be discarded and the assessment may be rescheduled.

(5) If the noise level determined in accordance with subsection (3) or (4) is—

(a) less than or equal to the maximum noise level specified in the relevant requirement imposed by or under the Act, the determination may be regarded as representing a true measurement for establishing compliance with the requirement, since, even with interference, the noise level is within the limit, or

(b) greater than the maximum noise level specified in the relevant requirement imposed by or under the Act, the determination must not be regarded as representing a true measurement for establishing compliance with the requirement since there may be interference.

(6) In this section—

Category A shot or Category B shot means a shot the noise level of which is classified as Category A or Category B, as the case may be, under this schedule, section 10.
