Assessment of excessive noise
Excessive noise complaints are investigated and the key wording in the definition of excessive noise is 'unreasonably interferes'.
This implies that noise can cause 'reasonable' interference. So the main issue for the noise control officer is to determine whether the noise is unreasonable or not when investigating noise complaints.
Factors that are taken into account when making this determination include:
- The activity producing the noise.
- The location of the noise source.
- Time of day or night.
- Duration of the noise.
- Noise history - have there been repeat situations.
- Noise level.
- Potential to stop the noise.
- Special audible characteristics.
The assessment is subjective and noise measurements are not required to be taken.
