- Stress, heart disease, ulcers, headaches
- Behavioural changes e.g. agression
- Disturb livestock and lead to injury and breeding failure
- Birds may abandon nests
- Non-Living Things
- Cause objects to vibrate at natural resonant frequency - stress cracks appear, causing structural damage (acoustic fatigue)
- Repetitive wheel vibrations damage infastructure
- Sonic bombs cause damage
- Living Organisms
- Industrial Noise
- Metal noise impact or explosive expansion of gases can cause problems
- Controls
- Ear defenders for workers
- Quieter equipment design
- Acoustic insulation to equipment
- Designing buildings to absorb noise
