What does pure tone audiometry primarily assess?
Pure tone audiometry measures an individual’s hearing threshold levels for specific frequencies.
Which unit is used to measure hearing thresholds?
Hearing thresholds are measured in decibels Hearing Level (dB HL).
What is the purpose of masking during pure tone audiometry?
Masking prevents the non-test ear from detecting the test signal.
Which frequencies are commonly tested in a standard pure tone audiogram?
The typical range includes 250 Hz to 8000 Hz, covering the spectrum of human speech perception.
What does the speech recognition threshold (SRT) assess?
SRT measures the lowest level at which a person can correctly repeat 50% of speech material.
What does a flat audiogram indicate?
A flat audiogram suggests equal hearing loss across all tested frequencies.

What is the purpose of bone conduction testing?
Bone conduction testing helps determine if the hearing loss is sensorineural or conductive.
Which symbols are used for air conduction on an audiogram?
Red circles (right ear) and blue Xs (left ear) represent unmasked air conduction thresholds.
What does word recognition testing evaluate?
This test measures how well a person can understand and repeat words at a comfortable loudness level.
