Statistical factors affecting machinery noise emission declarations

Stephen E. Keith, Stephen H.P. Bly

Abstract


The guidelines for machinery noise emission declarations in Canada are prepared based on ISO 4871[1]. It is important that there should be a reasonably high probability that the noise emission value of machinery should not exceed the declared value. The points to be considered are the number of machines used to determine the noise emission declaration, reproducibility of the measurements and the difference between the total standard deviation and the reference standard deviation of the measurements.
