Vehicle Noise

DPS Technical is well qualified and experienced to perform all modes of vehicle noise emission testing procedures. Primary acoustic testing is for exterior noise measurements of vehicles and components.

Our abilities and instrumentation enable us to perform both static (stationary) and dynamic (pass by) vehicle sound measurements utilizing fully calibrated “evidence” level equipment.

The testing conforms to guidelines as specified by EPA, TransportCanada, EC, Mexico and EU for all motor vehicles, ATVs, Mopeds, Scooters, Motorcycles, Cars, Trucks and Multi Use Vehicles etc.

All testing is performed in accordance with SAE or ISO methodology and suitable for use as summary of evidence for international vehicle and component certification.

Testing procedures utilized are as specified in the United States Code of Federal Regulations (CFRs) and suitable for EPA and Canadian certification and international homologation purposes.

The DPS test facility is compliant with vehicle sound testing site requirements as specified in EPA regulations 40 CFR 205, Subparts D, E, as well as in EU Directive 97/24/EC Annex VII, Physical Size, Acoustic Absorption and Texture Depth, etc.

Our specialized Noise Enforcement training module is a resource for individuals and communities to study and accurately measure “in use” motor vehicle sound levels such as Motorcycles, Snowmobiles, Watercraft, Cars, Trucks, etc.

Our sound measuring support program includes the ability to supply and performance-verify and calibrate vehicle sound measuring equipment.

Our Field sound measuring experience allows us to participate in noise measuring projects from recreational sources, industrial sources and to perform noise control outreach.
