Air Quality

Over 210,000 people suffer serious emotional, psychological or social effects due to noise in Barcelona, while more than 60,000 have serious sleep disorders. In addition, around 3% of annual deaths in the city are from cardiovascular illnesses that can be attributed to the same cause.

The city’s noise map shows that 57% of the population are exposed to traffic noise levels which are equivalent to or in excess of those considered negative for health by the WHO (53 dB), while 27% of the population are exposed to levels well above that threshold (65 dB). Traffic is the main source of noise in the day, while most noise at night comes from nightlife.

Measures to cut noise in the city

Work is currently being done on the Programme to Reduce Noise Pollution 2021-2030, which will implement measures to cut traffic and noise from nightlife and works.

The programme includes traffic-calming measures, nightlife awareness campaigns and sound limiters in venues, the reduction of noise at work sites, the rollout of the Barcelona Superblocks programme, sound-reducing asphalt and subsidies to improve insulation in residential buildings.

Twenty new sound sensors have also been acquired for areas which have undergone significant urban changes, such as superblocks, green streets and traffic-calmed streets. These sensors are an addition to the network of 133 units already installed in the city to monitor and interpret noise levels.
