Sound v noise
The government defines three levels of noise:
- No observed effect level – the level of noise exposure where there is no effect on health or the quality of life.
- Lowest observed effect level – adverse effects on health and the quality of life can be detected.
- Significant observed adverse effect level – the level of noise exposure where there can be significant effects on health and quality of life.
