ONE MORE CALIBRATION PROBLEM
You are calibrated to test at 45 degrees azimuth. However, the technician determined both sets of correction
factors and actually posted the correction factors for 0 degrees azimuth. You tested speech
reception threshold on a patient at 45 degrees azimuth and got 50 dB and applied the posted
correction factor of 5 dB so you wrote down 55 dB HL on the audiogram.
What is the actual threshold in dB HL?
What is the actual threshold in dB SPL?
