ISO 9614-1:1993 is an international standard that defines a method for determining sound power levels of noise sources using sound intensity measurements. It specifically outlines how to measure the sound intensity on a surface that surrounds the noise source, allowing for the calculation of the one-octave, one-third-octave, or band-limited weighted sound power level. The standard is applicable to any noise source where a stationary measurement surface can be defined.
