Concern with industrial noise created a need for a sound standard on all types of products. Noise
measurement, control and attenuation on gear driven equipment is dependent upon the individual
characterisics of the prime mover, gear unit, and driven machine – as well as their combined effects as a
system in a particular acoustical environment.
Proper assessment of these considerations is essential for realistic ratings.
The knowledge and judgment required to properly evaluate the various rating factors comes primarily from years of
accumulated experience in designing, manufacturing, and operating gear units. For this reason, the use of
this standard is not recommended for the engineering public at large.
