Industrial Sound Level Meter Magnetic Field Sensitivity Test, Report No. TC-P-010.
NIOSH 1976 Dec:15 pages
A test procedure is described for the determination of the effect on industrial sound level meter measurements of 60 hertz and 400 hertz magnetic fields having a field strength of up to one oersted. No data manipulation is required in order to obtain the magnetic field sensitivity: the information is available directly from the data sheet. The response of the sound level meter to a one oersted magnetic field and the magnetic field of up to one oersted is discussed.
