Working Party on Noise (GRB)

This page provides access to the documents and meetings of the Noise.
No new meetings have been scheduled as of today.

The Working Party on Noise (GRB) prepares regulatory proposals for consideration by the World Forum/WP.29 relating to noise emissions and sound-based alerting systems. The GRB not only considers noise limits on motor vehicles, but also minimum sound requirements as vehicles have become quieter, posing concerns for vulnerable road users such as pedestrians and cyclists.

The GRB typically gathers more than 70 specialists in sound-related areas from government agencies and non-governmental organizations around the world. The GRB facilitates international cooperation in research and analysis and supervises informal expert working groups that develop technical requirements on vehicle noise.

GRB usually convenes during February and September of each year.


Tyres were added to GRB’s responsibilities in 2019 pursuant to the conversion of GRRF into GRVA to address automated driving. Click here to access the Working Party on Noise and Tyres (GRBP) page.
