meter;
(b) the device shall produce sound of a stated frequency, within a
frequency tolerance of +1-5%;
(c) the manufacturer of the device shall provide with the device, any
data required in order to determine the sound level reading which

(ii) sound of a type mentioned in categories (ii) or (iii) of clause
1(1)(a), which is always higher than the permissible level or which,
when the sound is present, does not vary in level over a range of
more than 6 dB during the period of observation.
(2) Instrumentation
(a) Sound Level Meter
(i) A General Purpose Sound Level Meter shall be used for the
measurement of sound in categories (i), (ii) and (iii) of clause
1 (i)(a).
(b) Calibrator
An Acoustic Calibrator shall be used.
(c) Windscreen
A windscreen shall be used in all outdoor measurements.

Page 15 of 18
OFFICE CONSOLIDATION OF BY-LAW 91-56
(4) Use of Instrumentation
(a) Battery Check
If the sound level meter is battery powered the condition of the battery shall be
checked after the meter has been allowed to warm up and stabilize. The battery
condition shall be rechecked at least once per hour during a series of
measurements and at the conclusion of such measurements. The meter shall
not be used unless the battery condition is confirmed to be within the range
recommended by the manufacturer for proper operation.
(b) Calibration
The sound level meter shall be calibrated after the meter has been
allowed to warm up and stabilize at least once per hour during a series of
measurements and at the conclusion of such measurements.
(c) Sound Level Meter Settings
Measurements shall be taken using the following response settings:
(i) Slow Response (dBA)
The slow response and A-weighting shall be used for sound in
categories (i), (ii) and (ii) of clause 1(1)(a).
(d) Instrument Configuration
(i) Reflective Surfaces
The microphone shall be located not less than 1 metre above the
ground, not less than 1 metre from any sound reflective surface and
not less than arm's length from the body of the person operating
the meter. Not more than one person, other than the operator of
the meter, shall be within 7 metres of the microphone and that
person shall be behind the operator of the meter.
(ii) Microphone Orientation
The microphone shall be oriented such that the sound to be
measured is incident at an angle recommended by the microphone
manufacturer for flattest frequency response in a free field.
(d) Measurement - Slow Response
(i) Readings Taken
For sound in categories (i), (ii) and (iii) of clause 1(1)(a), a minimum
of three observations with a minimum observation time of 15
seconds each shall be made. The observed average reading for
each of the observations shall be noted as well as the minimum
and the maximum of the range of sound levels during each
observation period. If the difference between any two observed
average readings is greater than 3 dB, a minimum of six
observations shall be made.
