Mumbai’s Wadala was the second noisiest location in the country in 2017, says CPCB
Heavy traffic on Eastern Freeway and Metro work are the main factors behind high decibel levels, the Central Pollution Control Board saidmumbai Updated: Jan 23, 2018 10:19 IST
Wadala was the second-noisiest among 70 locations across seven major cities in the country where the Central Pollution Control Board (CPCB) measured noise levels in 2017. Jeedimetla in Hyderabad was the noisiest.
Wadala recorded 102 decibels (dB) at night , which is as loud as a home stereo system played at maximum volume, and 97 dB during the day — as loud as a hair dryer. The readings were the average of measurements taken over a 24-hour period. Of the nine other locations in the Mumbai Metropolitan Region where noise levels were recorded, Navi Mumbai, with noise levels of 80 dB during the day and 85 dB at night, was next on the list. Locations such as Bandra, Sion, Chembur, Andheri and CST recorded a spike in noise levels at night as compared to 2015 and 2016.
The CPCB said the movement of heavy vehicles — traffic on the Eastern Freeway — as the main cause for the high decibel levels. Ongoing Metro construction was another cause. D Saha, additional director, CPCB, said. “We will instruct the state pollution control boards from these cities to carry out an analysis of the data and carry out individual studies at each location.”
Excessive noise can affect the health and well-being of citizens, and continuous exposure to levels above 80dB could lead to partial hearing loss, according to the World Health Organization (WHO). Doctors said the average ambient noise levels were high and continuous exposure could lead to health ailments. “People living in close proximity to these busy traffic junctions or highways can develop noise-induced hearing loss over time or permanent deafness.
Short-term exposure could lead to ear-drum damage. Mental health illnesses and anxiety leading to hypertension are some of the other effects,” said Dr Abhishek Khond, resident doctor, ENT department, Sir JJ Hospital and Grant Medical College.
