In pure tone audiometry, the red line on the audiogram represents which of the following?
Show Hint
Remember the mnemonic: Red for Right ear.
Updated On: Jun 24, 2026
- Bone conduction
- Air conduction
- Right ear
- Left ear
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: In a pure tone audiogram, separate symbols and colours are used for each ear so the examiner can tell them apart.
Step 2: By convention the right ear is plotted in red (symbol O for air conduction), and the left ear is plotted in blue (symbol X for air conduction). A useful memory aid is RED for Right.
Step 3: Air conduction and bone conduction are distinguished by the symbol shape, not by the red colour, so options a and b are incorrect.
Step 4: Since red denotes the right ear, the correct answer is right ear.
