Week 13 Noise pollution in construction period

(Source: Google image, 2016)

The main pollution of construction period contains noise pollution, dust pollution, mud suspended solids pollution, light pollution and solid waste pollution etc.. Noise is one of the most common problems in building construction. The main hazards of noise pollution in the construction site are list below: Firstly, occupational deafness: a progressive hearing loss, until the two ears roar and auditory failure. Secondly, explosive deafness: refers to a high intensity noise (often more than 130-160dB) caused by hearing damage, the performance of the ear drum damage, and mix with a concussion, etc. Thirdly, noise pollution in addition to the impact of the above may also cause neurological disorders, gastrointestinal disorders etc. Noise can cause hearing loss and this loss is gradual. Noise in addition to the impact of hearing loss and also may cause high blood pressure, heart disease, etc. Moreover, noise will distract people's attention, so it is often cause accidents.

There are three ways to control noise: Firstly, eliminate and reduce the production of noise sources: Using the silent tools instead of sound tools, such as hydraulic machine instead of forging machine, hydraulic riveting machine instead of the machine rivet, welding instead of riveting etc. Secondly, control the spread of noise: Rational distribution and separate the high noise places and other space. Installing muffler on noisy mechanical devices. Thirdly, strengthen personal protection: Strengthen publicity education, so that workers know the harm of noise, and consciously make personal protection.
