Noise Pollution

Noise pollution came after the Industrial Revolution. With the overwhelming population growth with the industrial development and technology of noise pollution, one of the problems in the big cities has gained a great share, and this factor, like other environmental pollution, has a huge negative impact on humans, animals and plants. Nowadays, machine life has made human beings more tolerant in stressful environments with noise sources. In the environment, there are various factors that make man-made and natural sounds produce sound levels ranging from zero to zero hearing loss. Painfull threshold of 130 dB that results in hearing loss.

What is noise pollution?
Noise pollution is the abnormal and disturbing sound of humans, animals, and machinery that destroys human neural activity, and high levels of noise often cause damage to the nervous system and auditory nervous system, particularly in children and adults. it creates.

The unit of noise is a decibel (db)and based on air pressure variations, it ranges from zero decibels (hearing thresholds) to 130 decibels (deafness thresholds). Installed on sound measuring devices. Zero to 40 dB is sound tolerable. Hearing 100 dB for 10 minutes requires a rest of 20 minutes in a quiet environment to counteract the effects of noise.

Factors of noise pollution:

• Factories
• Construction work
• Noise from home ventilation
• Transportation noise (aircrafts, rails, cinemas, high-speed cars, etc.)
• hotel and restaurant speakers

National standard of sound pollution quality for Afghanistan:
This standard was prepared in 2013 by the Technical Standards Committee chaired by the Honorable Engineer Gholam Mohammad Malikyar, National Directorate of Environmental Protection, in cooperation with other relevant bodies, and by the Honorable Supreme Council of Standards, headed by Mr. Karim Khalili. The second vice presidency was approved at the time.

Noise pollution Damage to human Health:

• Loss of hearing power
• Nervous allergy, muscle cramps, hypertension, mental and physical exhaustion, loss of body balance, suicidal tendency to murder, impaired vision, heart disease, gastrointestinal swelling and dyspepsia, paleness.

Challenges of noise pollution in Kabul city:

• There are more than thousands of generators in the city
• Restaurants
• Wedding hall
• Motor vehicle noise
• The sound of explosions
• Flying planes at low altitudes
• Installing non-standard horns in vehicles
• Ice-cream Mobile Dealers

How to prevent noise pollution:

• Noise levels in workplaces where workers are constantly exposed to brain activity should not exceed 10 db.
• Try to avoid machines that produce too much noise.
• The sound of factory machines should not reach outside the factories.
• Try to avoid the creation of residential units adjacent to airfields.
• Restrict and prohibit the passage of lorries and trucks.
• Creating a belt of trees and vegetation that cuts the sound level by 10 db.
