Sources of Noise Pollution Noise pollution is mainly caused by the following factors: • Traffic Noise • Construction Noise • Industrial Noise • Aircraft Noise • Domestic Noise
Traffic Noise • Noise is given off from the engines or horns of vehicles like buses and cars. • When they travel at a higher speed, the noise is greater.
Construction and Industrial Noise • The construction work (e.g. piling) usually lasts for 3-5 hours per day and produces a lot of noise. • Some noise is generated from machinery and air-conditioning in factories.
Aircraft and Other Noise • During the take-off and landing of flights, the noise produced by planes is great. • Shops on the street usually play music or promote products at a high volume. • Noise is also produced by the public in densely-populated districts.
Impacts of Noise Pollution • Effects on human • Disturbing people's thoughts and feelings • Causing different diseases • Effect on government and industry • Time lost on the job • Payments of worker's compensation for diseases
Hearing Loss • A result of society's rising levels of noise • A common occupational and environmental hazard • The risk has spread to young adults
Solutions Heavy industrial area should be separated from residential areas Using noise attenuating materials and construction techniques
