All new electric and hybrid vehicles are now legally required to have an external sound generator so they can be more easily heard by pedestrians and cyclists.
The EU-mandated system is called an Acoustic Vehicle Alert System, or AVAS. It becomes law on 1 July 2019 after years of campaigning by groups such as the European Blind Union.
AVAS systems need to work at speeds of up to 13 mph, and the volume must be at least 56 dB (similar to the volume of an electric toothbrush).
The volume must not be louder than 75 dB, equivalent to the noise of a conventional car
The sound must also be continuous, and help road users understand the driving behaviour of the vehicle by sound alone – for example, by varying in volume and pitch when a vehicle is accelerating.
Harman, a supplier to the car industry, is already fitting its ‘external Electronic Sound Synthesis’ (eESS) to new cars, after developing it since 2009.
It works via speakers at the front and rear of a vehicle. It uses a speed sensor, and another sensor on the accelerator pedal, to meet the EU requirements of signalling a vehicle’s characteristics by sound.
The new law, applicable to all new silent electric cars and hybrid vehicles, comes into force Europe-wide on 1 July 2019. It applies to any vehicle with four or more wheels – which means electric motorcycles are not required by law to have it.
‘Silent’ electric cars must legally now make a noise

As Gloucester had mentioned as of today the Law comes into place here is a comment from the Mail and it does quote that the Leaf already has this system.
