In a world where there is a drive for everything to be quieter, vehicle noise measurement and control is a growing application. If measurements need to be made to ISO 5130:2007, which is an internationally recognised standard for vehicle exhaust noise testing, a more detailed measurement needs to be made. ISO 5130:2007 requires three consecutive measurements to ensure repeatability. These measurements are taken at a specified engine speed, or RPM, and the maximum sound level produced during the test is taken.
