Noise pollution a new threat in Nepal

Apart from various kinds of environment pollutions, "noise pollution" too has become a tough challenge for human health in Nepal.
WHO have already said that the safe noise level for a city is 45 decibels. The continuous noise levels in excess of 90 decibels can cause loss of hearing and irreversible changes in nervous system. However, in Nepal there is no provision for measuring and controlling the noise level.
In the developed countries, the noise level exists in low level even though the number of vehicles is very high. But in Nepal it is the just opposite- number of vehicles is low and the level of noise is high, said Dr. Mathura Prasad Shresth, chairman of Sources Center for Primary Health Care (RECPHEC).
Due to the uncontrolled and unnecessary noise pollution produced by several motorbikes and another vehicles, the people living at the city are at a high risk of various health hazards, he added.
Due to the effect of noise pollution, people may suffers from the maladies such as hard hearing, hearing loss, fatigue, irritation, headache, speech and sleep disturbance, high blood pressure, cardiovascular disease, digestive problem, nausea, lack of concentration and decreased performance, the RECPHEC informed.
Speaking at a press conference organized in Kathmandu Tuesday, Shanta Lal Mulmi, executive director of RECPHEC informed that the organization was bringing programmes against noise pollution within a week at Bir Hospital.
W have been planning to launch a noise measuring mechanism in five high-crowded cities of the nation, he added.
We can measure the increased and decreased level of noise every day, which will help pressurize the government to mention the level of noise during policy making process, he stated.
RECPHEC suggested the government should make policy about noise pollution and Transportation Entrepreneurs should follow it strictly.
According to Dol Nath Khanal, general secretary of National Federation of Nepal Transportation Entrepreneurs, " we are ready to implement any direction to control the noise level in the country."
Kamana Singh Khatri, sub-inspector of traffic police, stated that she had lost her hearing capacity owing to noise pollution in the city.
Traffic police persons are the main victims of noise pollution. Similarly, pregnant women also should be careful of the noises created by the unnecessary blaring of horns.
According to the report, people have only 26 decibel of hearing capacity. However, a horn in a general vehicle produces more than 100 decibel of sounds. People can only bear around 60 dB of noise. Noise more than 70 dB is harmful for human health, experts said.
