Acoustic Determinator Type 7816 is a very convenient and intuitive tool for acoustic engineers who want to find out the sound power level of industrial sources by measuring sound pressure levels in the field. Using data from field measurements, ...more

Sound Power has become the preferred quantity to measure when determining product noise emissions. This is because it is an absolute quantity, dependent only on the noise source itself, and independent of the acoustic environment. Sound Pressure, on the other hand, is dependent on both the noise source and on the acoustic environment. ...more
