Appendix (1) - Requirements for Monitoring Noise Levels
First: Information to be Recorded
The following information should be recorded for audit and reporting purposes:
1. The date, time, location of the measurements and the name of the operator undertaking them, in addition to the photographic records for each measurement location.
2. The type of instrumentation including serial numbers of all elements of measurement system and the calibrator used, the measurement procedure and any calculation used
3. The settings of the sound level meter including the dynamic range, slow or fast response, etc.
4. A schematic map of the area showing:
a. A description of measurement locations
b. Nearby sensitive noise receivers
c. Location of potential future noise receivers within the area
d. Details of the nature of the ground between source and measurement position, i.e., acoustically hard or soft ground
e. The nature and form of any barriers between source and receiver
f. Any significant noise sources other than the specific noise source under investigation.
5. A description of the time aspect of the measurements. i.e., the reference and measurement time intervals, including details of sampling, if used
6. Measurement positions including microphone height above ground and distance from reflective surfaces
7. Where appropriate, a description of the sound propagation model used
8. The following conditions during the measurements should be described qualitatively and quantitatively where appropriate:
a. Precipitation
b. Wind speed and direction
c. Presence of conditions likely to lead to temperature inversion (i.e., clam nights with little cloud cover)
d. Relative humidity
e. Variability and character of noise emission sources

Second: Measurement Conditions
1. Where possible, maximum effort should be exercised in monitoring noise levels during meteorological conditions that are approximately consistent with the following:
a. Wind speed between 1 and 5 meters per second
b. Wind direction within an angle of \( 45^{\circ} \) of the direction connecting the dominant sound source and the Center of the specified measurement area
c. The wind direction comes from the specific noise source towards the noise receiver
d. There should be no strong temperature inversions near to the ground
e. There should be no precipitation
f. The ground should not be wet, or snow covered
2. For all noise measurements:
a. There should not be any electrical and electromagnetic interference (i.e., nearby power cables, radio transmitters)
b. The axis of maximum sensitivity of the microphone must be directed towards the noise source
c. For all measurements, the microphone must be fitted with a wind shield as recommended to be appropriate by the manufacturer/supplier. Noise from wind acting directly on the microphone or on the nearby structures or vegetation should not interfere with the measurements
3. In the case these conditions cannot be met, details of the adverse conditions should be recorded for information and additional measurements may need to be undertaken as appropriate
4. Taking into consideration clause (3) of this section, if any of the conditions set forth in clauses (1) and (2) cannot be satisfied, the Center shall take into account the impact of these measurement conditions on the operator's ability to comply with the specified noise standards.
