Environmental noise is a major issue in most countries, especially in areas of high population, and the sources of noise and their adverse effects on our well-being are varied. In terms of assessing the impact of these issues, we need to be able to make suitable noise measurements, or in some cases monitor the noise levels for longer periods.

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.
