Campaigning against the deafening noise in Dhaka
| 01:30 mins.
Mominur Rahman has embarked on a one-man anti-honking campaign in Dhaka, one of the world's noisiest cities. The World Health Organization says humans can only tolerate a maximum of 85 decibels for eight hours, over a period of time, before hearing damage occurs. But residents in Dhaka, a city of 18 million people, are regularly exposed to noise levels of up to 110 decibels.
