normal weekdays (six consecutive Leq/5min readings);
¡P
One set of measurements between 1900-2300 hours;
¡P
One set of measurements between 2300-0700 hours of
next day; and
¡P
One set of measurements between 0700-2300 hours on
holidays (three consecutive Leq/5min readings).
4.1.3.
For
the latter 3 sets of measurements specified in Section 4.1.2 above, one set of measurements
shall at least include 3 consecutive Leq (5min) results.
4.1.4.

Prior and after to the noise measurement, the meter was checked using
the acoustic calibrator for 94dB (A) at 1000 Hz. If the difference in the
calibration level before and after measurement was more than ¡Ó1 dB (A), the
measurement would be considered invalid and repeat of noise measurement would
be required after re-calibration or repair of the equipment.
(g)
Noise measurements shall not be made in fog, rain, wind with a steady
speed exceeding 5m/s or wind with gusts exceeding 10m/s. The wind speed shall
be checked with a portable wind speed meter capable of measuring the wind speed
in m/s.
4.1.9.
Maintenance
and Calibration
(a)
The microphone head of the sound level meter was cleaned with soft cloth
at regular intervals.
(b)
The sound level meter and calibrator were calibrated at yearly
intervals.
