The methods employed for noise control in buildings are explained in the following: 1. Wall Mass and the Thickness are Increased The massiveness of a material is an efficient parameter that resists noise. Hence concrete walls are more insulating than wooden walls.

CEMENT INDUSTRY POLLUTION CONTROL MEASURES.

Noise is generated from operation of heavy duty machines - crushers, tube mills, ball mills, fans, coolers etc. Noise level depends upon nature, size and capacity of machines, running speed, feed material etc. The noise level generally varies from 70 - 118 dB.

THERMAL EXPANSION AND CONTRACTION - Penn State College of Engineering

An average value for the coefficient of thermal expansion of concrete is about 10 millionths per degree Celsius (10x10 -6 /C), although values ranging from 7 to 12 millionths per degree Celsius have been observed. This amounts to a length change of 1.7 centimeters for every 30.5 meters of concrete subjected to a rise or fall of 38 degrees Celsius.

Hazards and Control Measures for Demolition Work

Additionally, you should try to work in a well-ventilated area to reduce the noise level. If the noise level is still too loud, you may need to use sound-blocking earmuffs or earplugs. 10. Electric Shock One of the most serious hazards associated with demolition work is electric shock.
