Question 15
IH device uses the following scale for personal noise to comply with the OSHA
PEL-TWA
Select one:
O a. B-scale
O b. A-scale
O. C. C-scale
O d. A, B and Hertz scale
Oe. B, C and Hertz scale
Question 13
Why does OSHA recommend A-scale on dosimeters and SLMS for personal noise
levels?
Select one:
O a. The A-scale attenuates noise from the industrial equipment/device.
Ob. The A-scale adjusts noise at each octave band to match the human
hearing
Oc. The A-scale is a NIOSH tool to evaluate engineering control against noise.
The A-scale is a DOD tool to evaluate engineering control against noise
O d.
Oe.
The A-scale is less accurate/precise than the C-scale on dosimeters and
SLMs.
