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:
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.
