Some additional info on the subject.
The noise measurement used in OSL races is an "A" type. This type of measurement takes the limitation of the average human hearing ability into consideration. So waves below and above a specific frequency are to be considered as not part of the noise.
The other type is the "C' type. This type does not take the average human hearing ability into consideration but allows all harmonic sound waves to be measured.
