Methods Used For Environmental Noise Control

By Tiffany Gill


It is a fact that excessive levels of noise can lead to negative effects on human beings in the long run. It is really important to find out effective methods of environmental noise control in order to make sure that human environment remains clear of any noise pollution that could prove to be harmful. It is not a healthy thing to live in any space that is polluted heavily because it impacts your personal well being as well as your ability to work efficiently.

Excessive or loud noises are a part of everyday living. Whether you go out for work or stay at home vibration and noise is just enforced into the surrounding environment and when individuals get exposed to extremely high levels it can cause adverse physical as well as psychological effects. Common problems that could be caused include loss of hearing, headaches, severe migraine, increased stress levels and much more.

Human health is exposed to great risk which makes it essential to come up with effective control techniques in order to work towards the betterment of your community environment. The control techniques that you can choose are plentiful out there but among them four are those that are regarded as basic methods and used more frequently than other techniques. The basic or main purpose of all these methods remain the same and that is to gather protection for personal well being and the surrounding environment from getting polluted in this manner.

One of such method is sound insulation, this can be done by installing solid barriers throughout the space in order to limit the amount of sound that can be created. This particular method enables to block sound waves that could cause harm. If the barrier is strong enough, it gets difficult for any type of sound to penetrate through. Usually steel or concrete is used for this purpose.

Noise absorption is another particular techniques used by many individuals. The basic purpose of using this technique is to convert sound energy into heat energy while using porous materials like foam sheet or sponge that help in the process of absorption. All the loudness present in the air is absorbed and you are left with natural sounds only.

A method similar to sound absorption is vibration damping but this particular method is used to actually cut down excess sound waves that are created from solid surfaces rather than waves. For instance, loud noises created from hammering, loud thumps, etc. It works best if there is too much vibration in your surrounding atmosphere that you want to get rid of.

Besides these, vibration isolation is another control technique that enables to protect a specific area or space from the loud unwanted source of sound. An area can be isolated or made sound proof by placing physical barriers that are able to block out any unwanted nuisance.

All such methods prove to be extremely effective when it comes to environmental noise control. In order to decide which technique could prove to be more useful than the other you have to understand the nature and dynamics of a particular sound and then choose an appropriate method to control it.
