Sound power is a measure of the acoustic power generated and radiated by a machine or tool. This measure characterizes and quantifies the sound source, independently from the environment. Sound power measurements are used to certify tools towards specific ISO standards. Beyond certification on local markets and tool labeling according to regional regulations, accurate sound power measurements may have a striking impact on export sales and branding strategies. It is crucial therefore not to exceed the allowed sound power level in many industries. Moreover, lower sound power often represents a competitive advantage.
Sound power testing is used across a wide variety of industries such as white goods, office equipment, hand-held power tools or off-highway vehicle industries.
