What Is Noise Pollution, How Does It Occur and How Is It Prevented?

Noise pollution, also known as noise pollution, is any human, animal or machine-induced noise that negatively affects human or animal life and disrupts its balance. One of the most common forms of noise pollution is pollution, especially from motor vehicles.


The most common type of noise around the world is caused by transportation systems. In addition to motor vehicles, the noise created by aircraft and railway vehicles also has an important place. Mistakes in city planning may cause industrial and residential areas to adjoin each other, and as a result, noise pollution created by the industrial area can have adverse effects on the health of those living in neighboring settlements. Other factors that create noise pollution include car alarms, emergency sirens, various white goods and household appliances, factory-machine sounds, construction and repair work, noisy animals, sound systems, speakers, matches, entertainment, religious social activities.

Human health effects

The effects of noise on human health can occur in both health and behavioral directions. In general, all kinds of noise, called noise, affect human health physiologically and psychologically. These unwanted sounds can cause many consequences such as nervousness, aggression, hypertension, high stress, tinnitus or ringing in the ears, hearing loss, sleep disturbances.

Among these results, while stress and hypertension can lead to serious health problems, tinnitus and humming can cause forgetfulness, serious mental depressions and sometimes panic attacks.

Noise control

The control hierarchy concept is used to reduce noise in the environment or workplace. Engineering noise controls can be used to reduce noise propagation and protect individuals from excessive noise. If noise control is not appropriate or sufficient, individuals can take steps to protect themselves from the harmful effects of noise pollution. People can protect the hearing health of their ears by using hearing protection devices (eg earplugs or earplugs) if they are required to be in a loud environment. In recent years, Buy Quiet programs and initiatives have emerged in the US to combat occupational noise risks. These programs encourage the purchase of quieter vehicles and equipment and encourage manufacturers to design quieter equipment.

Noise from highways and other urban factors can be reduced by urban planning and better road design. Roadway noise can be reduced by using noise barriers, limiting vehicle speeds, changing the road surface texture, limiting heavy vehicles, designing better tires, using traffic controls that improve vehicle flow to reduce braking and acceleration. Creating a computer model targeting local topography, meteorology, traffic operations and the desired minimum amount of noise to reduce road noise is important in the implementation of these strategies. If these solutions are investigated in the project planning of the road, the noise reduction costs in the building are also reduced.

Aircraft noise can be reduced by using quieter jet engines. Changing the flight path and runway usage time during the day also benefits residents living near the airport.
