Sound power is a quantity that indicates how much a source radiates sound. This quantity cannot be measured directly. It can be determined measuring sound pressure by the use of microphones placed around the source (according to ISO 374X standards for instance) or measuring sound intensity (according to ISO 9614). The sound power is independent from the source environment, enabling to compare the sound power of a source with the sound power from another source measured somewhere else.
OROS Sound Power solution is ideal for the automation of sound power measurements according to ISO 3744,3745,3746 on indoor as well as outdoor test benches.
