Acoustic EngineeringCustomer RequirementsNoise emission legislation is defining clear targets for the sound levels. Even more pressure is generated by the operators of the vehicles, who are exposed to the noise for up to 10 hours a day.
Increasingly the noise level of a vehicle is regarded as a sales argument and provides a potential competitive advantage. The sound quality is heavily influencing the quality and performance perception of a product and will therefore contribute to a positive image of your product.
Especially in non-road applications and tractors, one of the major sources for noise is the fan of the cooling system. The optimum solution is the right trade off between efficiency, cost and noise level.
