Is your city loud? Do you often hear cars driving by and even honking? Has that affected your health?

In this video, YouTuber Not Just Bikes explains the many dangers of noise pollution and pinpoints where most of it comes from cars.

But first, what is the acceptable limit for noise pollution? The World Health Organization (WHO) says that cities should not be louder than 55dB. In fact, noises over 85dB can cause hearing loss. That's quite scary if you think about it, as many cities surpass that limit.

About 65% of Europeans live in cities with noise levels above the WHO's limit. Even worse, Cairo, Egypt, averages 90dB during the day (into the range of permanent hearing loss), and in Karachi, Pakistan, rush-hour noise levels have been measured at over 140 dB.
