For vehicle buyers, the noise exposure to passengers of buses and coaches can be as important as it is for cars. Local authorities can set very demanding noise limits for their transport fleet, a good example being the ‘Transport for London’ requirements. The quality and comfort of coach transport is ever increasing but needs an increasingly comfortable acoustic environment to match.

Ventac uses sophisticated noise measurement techniques to identify the multiple sound pathways from the noise sources to the passengers. This process includes the generation of noise maps across the vehicle partitions to pinpoint noise ‘Hots spots’. These measurements allow for the optimisation of noise control packages which is can be important cost of the package and for fuel consumption of the vehicle.

The growth of electric and hybrid vehicles has led to new acoustic issues for vehicles. Annoying tones can be a problem on these vehicles particularly when they aren’t masked by engine noise.

Engineering solutions to meet the TIER IV emission requirements can result in new heat sources in the engine bay. Ventac noise control composites can be designed meet these special heat resistance requirements.
