The 21st session of the Task Force on Vehicles Sound will be held on Tuesday 9th June 2026 from 13:00 to 17:00 (CEST) as a hybrid meeting in Gothenburg, Sweden. The agenda includes adoption of the agenda and report of the 20th session, exchange of information on national and international requirements with presentations on anoise figures in vehicle certificates of conformity versus perceived noise" and on “transportation noise and cardiovascular health”, cross-matrix follow-up discussion, discussion on updating the guidelines of the task force as approved in GRBP-74-03 Rev.1, any other business, and determination of next meeting and provisional agenda.

NEFOM and S.O.S. represent over 1 million European citizens experiencing noise from light vehicles inconsistent with Certificate of Conformity figures. The LENS project conducted 2300 measurements of 2300 vehicles, finding measured noise levels in practice much higher than type approval, sometimes reaching 100 dB(A). The A-filter used in Certificates of Conformity is unsuitable for noise levels above 70 dB and does not represent human perception. Sound limits for motorcycles have not changed since 2015 and remain too high. The document requests further improvements to RD-ASEP testing, replacement of the A-filter with a C-filter, and significant reduction of sound level limits for motorcycles.

Over 130 million people are affected by transportation noise, an important risk factor for disease burden. Road traffic noise increases cardiovascular risk by approximately 3.2% per 10 dB increase and all-cause mortality risk by approximately 5.5%. The WHO road-noise guideline of 53 dB Lden may not be sufficiently protective, as mortality risk increases at lower noise levels. Night-time noise increases blood pressure and is associated with increased use of sleeping medication. Aircraft and road traffic noise can increase blood pressure, disturb its normal daily rhythm, and contribute to hypertension. Reducing residential noise exposure should become part of cardiovascular prevention.
