This coastal city is India’s noisiest

The red light at a traffic junction is the universal sign for vehicles to stop — but in India, it is also a signal to start something else: relentless honking. To address this menace and punish impatient drivers, the Mumbai Police have launched a novel ‘Honk More, Wait More’ scheme. Now, if impatient drivers honk at signals, they are simply increasing their wait time.
 
This may seem a quirky solution but it addresses a serious problem. When noise from constant honking is added to the general cacophony in cities, it becomes noise pollution — and this pollution can be costly and dangerous too.
Because of the threats of noise pollution, the Central Pollution Control Board (CPCB) tracks noise-levels through monitoring stations spread across India’s major cities. In 2018 (the latest year for which data was available), Chennai was the noisiest among India’s six metros. 
 
Across the city’s 10 stations, the average noise levels during the day was 67.8 decibels (dB), much higher than the equivalent figure for Delhi (61). Since decibels are measured on a logarithmic scale, a 10 dB increase actually translates to a doubling in perceived loudness making differences between cities more significan
