Acoustic measurements can deliver several parameters. The typically used one are sound power level and
sound pressure level.
Sound power is the sum of noise emitted over the whole surface of the device.
Sound pressure is typically measured in 1m distance in front of the housing and represents the noise exposure
at this position in an certain ambient.
