Engine noise from vehicles

- Award Criteria
The main purpose of the environmental criterion is to reduce engine noise from vehicles in built-up areas with low speed limits and thereby contribute to a better residential environment.
Suppliers that offer cars with a noise level of lower than 72 dB(A) will be awarded points on a scale of 0-10 where 10 points is the best.
Documentation of the Requirement Specification:
Information about noise emissions is not readily available.
The tenderer can document the noise level per vehicle model as specified in EU type-approval. The information that must be stated can be found under "Test results" and "Sound level of moving vehicle: dB(A)".
Annex 1 of the Vehicle Regulation stipulates maximum permitted levels for noise depending on the vehicle's power to weight ratio. The statutory requirement is based on Regulation EU 540/2014 on the sound level of motor vehicles and of replacement silencing systems, Annex III.
The criterion's weighting must be assessed in relation to the organisation's overarching climate and environmental objectives. It is important that the buyer sets a requirement of 72 dB(A).
Difi's power output meter can be used to show the climate and environmental effects of the selected requirement and criterion in a given reference scenario.
