Noise cameras detect and monitor sound emitted from a vehicle that exceeds a limit that has been set. They may also be referred to as acoustic cameras, with the aim to catch drivers who make excessive noise with their engines.
In the UK, it is illegal to modify exhaust systems to increase noise and power. However, this hasn't stopped some owners getting their cars modified. The rollout of noise cameras aims to clampdown on drivers who use illegally modified exhausts to break the legal noise limit in local communities, and help to reduce noise pollution to improve wellbeing.
Noise cameras operate in a similar way to speed cameras. They feature a microphone that can differentiate between sounds, such as a car?s engine, a horn or a radio, by monitoring sound patterns.
They are fitted with an automated number plate recognition (ANPR) system that captures a numberplate when a vehicle is exceeding noise levels as this activates the noise camera's microphone. The police are then alerted, receiving a report that confirms what action should be taken - this could either be a hefty fine or lead to prosecution.
Vehicles that are manufactured from 2016 onwards have a legal sound limit of 72 decibels (dB). In 2026, this will decrease further to 68 (dB).
As it stands, noise cameras are currently in operation in four locations. This includes Bradford, Birmingham, Bristol and Great Yarmouth as part of a trial. Should these trials be successful, noise cameras could see a more widespread introduction across the UK.
