Being exposed to traffic noise on a regular basis raises the risk of depression by almost two thirds, a study shows.

Scientists tracked thousands of people living in Amsterdam over a four-year period, measuring noise levels round-the-clock.

Results - Decibels - Db - Cent - Risk

The results revealed those regularly exposed to over 70 decibels (db) were 65 per cent more at risk of depression than those exposed to just 45-54db.

Researchers studied 23,000 men and women aged 18 to 70 from inner-city Amsterdam.

Postcodes - Traffic - Noise - Records - Parts

They matched their postcodes with traffic noise records from different parts of the city and got volunteers to complete frequent questionnaires designed to detect signs of depression.

High noise levels were defined as anything over 65 decibels. A passing diesel lorry generates around 85 decibels and a motorbike roughly 100db.

Findings - International - Journal - Hygiene - Environmental

The findings, in the International Journal of Hygiene and Environmental Health, revealed those forced to listen to 70db or higher on a regular basis had much higher rates of depression.

In a report researchers said: 'This study provides new evidence of an association between high road traffic noise exposure and depressed mood.'

It’s estimated that in London alone 1.6 million people are exposed to traffic noise at dangerously high levels.
