The noise of the city - police sirens, train announcements and the constant drone of cars - can often be drowned out by listening to some calm music.

Or, people simply get used to it.

German researchers collected information from over 200,000 hearing tests worldwide.

Dubbed the ‘Mimi data’, they investigated a possible correlation between living in a city and premature hearing loss using the Mimi app.

They calculated participants’ hearing age, and found a 64 per cent positive correlation with noise pollution levels in the cities.

This implied that hearing loss may be directly or indirectly attributed to living in cities with especially high noise pollution.

With that in mind, here is a map - the darker the colour, the more prevalent the noise pollution:
