Noise Pollution

Any unwanted and excessive sound that affects human health, wildlife, or the environment is referred to as noise pollution. Noise pollution can be transport noise, vehicle noise, industrial noise, construction site noise, neighborhood noise, or any loud activity in a surrounding area.

Noise Pollution

Causes and Sources of Noise Pollution

  • There are two sources of noise pollution: natural and man-made.
  • Volcanic eruptions, lightning, and ocean waves are examples of noise pollution caused by natural sources.
  • Industrialization, vehicle honking, construction sites, household appliances, events, and loudspeakers are potential sources of man-made noise pollution.

Effects of Noise Pollution

Not only is human health affected by noise pollution, but it also creates a disturbance for animals and birds. Hypertension, frustration, anger issues, hearing issues, disturbed mental health, sleep disorders, cardiovascular diseases, and many more are caused by noise pollution. Therefore, it is essential to minimize noise pollution in our surroundings to have a peaceful mind and life.

Noise Reduction

The method of removing or somehow reducing the noise level coming from the source is called noise reduction. Our industrial areas work with lots of heavy machinery, which results in a huge amount of noise pollution. This noise affects the surrounding environment and is harmful to the workers working in the vicinity. There are many methods for noise reduction. Some of them are discussed below.

Methods for Noise Reduction

  • Proper installation, management, and cleaning keep the machinery working smoothly.
  • To put the system in a container with acoustic barriers.
  • Damping is the method to reduce vibrations produced by noise in applications such as hoppers, panels, tanks, and chutes.
  • The damping method has two techniques: layer damping and constrained layer damping. Bitumastic damping material is stuck to the surface in layer damping, and in the latter, there is a laminate construction.
  • Airborne noise pollution can be handled by fitting foam or fiberglass in the ducts that penetrate the walls.
  • Placing exhaust and fans in the right place also helps in reducing noise pollution.
  • Fitting silencers on the exhausts and using pneumatic nozzles for drying and blowing can also help.
  • Using quiet electric motors and quieter timing belts can also help in noise reduction.

Products Used for Noise Reduction

Many different types of noise reduction products are available in markets, and these are made of special materials such as cellulose, polypropylene, vinyl, and composite.

Acoustic Barriers

  • These are high-performance barriers used to control industrial noise pollution.
  • These are easy to install, durable, heat resistant, lightweight, and with one or two absorbent sides.
  • Acoustic barriers are used in transport, sports facilities, utilities, and the mechanical parts industry.
  • These barriers are galvanized with powder coating, vinyl coating, mild steel, or aluminum.

Acoustic Enclosures

  • Acoustic enclosures are metal containers that are formed outside the machinery.
  • These enclosures reduce noise and help in smooth working.
  • Acoustic enclosures have an air inlet drive for combustion and also have acoustic windows, doors, panels, and ventilators.
  • These enclosures can be used for indoor and outdoor units.
  • The finishing of these enclosures is of aluminum, steel, galvanized steel, and syntha pulvin.
  • These are used for test cells, personal space enclosures, compressor enclosures, and soundproof control rooms.

Acoustic Canopies

  • Acoustic canopies are designed to be lowered down on the machinery.
  • These are used in applications where the system requires proper ventilation.
  • These can be used for indoor as well as outdoor units.
  • These are commonly used for gas and diesel turbines, generators, compressors, etc.
