Sound generated by stationary farm equipment reduces by the square of the distance from the equipment. When distance doubles, sound levels typically drop 6 dBA. So, 90 dBA at 5 m (16 ft) is 84 dBA at 10 m (32 ft), 78 dBA at 20 m (66 ft), and so on. Because of atmospheric and surface effects, sound levels rarely decrease exactly 6 dBA with ...

NC

Noise Criterion - NC - were established in the U.S. for rating indoor noise like noise from air-conditioning equipment and similar. In Europe it is common to use the alternative Noise Rating Curve - NR.. The method is based on a measurement of sound pressure levels and a set of sound pressure criteria curves ranging frequencies from 63 to 8000 Hz - and a tangent rating procedure.
