PARLIAMENTARY WRITTEN QUESTION
Motor Vehicles: Noise (4 June 2020)

To ask the Secretary of State for Transport, what (a) progress has been made on and (b) the preliminary results are of the acoustic camera trials announced in June 2019 to monitor traffic noise.

Asked by:
Andrew Griffith (Conservative)

The acoustic camera trial is completed and the results are awaiting publication. Preliminary indications are that the device can identify individual vehicles in certain circumstances and assign noise levels to them but further development is needed to improve accuracy.

The technology has the potential to identify excessively noisy vehicles, however, there are still difficulties in measuring noise in an uncontrolled environment to be overcome.
