What is the symbol for unmasked air conduction in the left ear?

• A. O
• B. X
• C. >
• D. <

Answer: (B)

The symbol for unmasked air conduction in the left ear is represented by an "X." This notation is widely used in audiograms to clearly indicate the results of air conduction audiometry specific to the left ear. Each symbol helps differentiate between various types of hearing tests and the respective ear being assessed. For example, the "O" symbol typically indicates unmasked air conduction in the right ear, while the symbols ">" and "<" are used for bone conduction testing in the right and left ears, respectively. Understanding these symbols is crucial for accurately interpreting audiometric data, which aids in diagnosing hearing issues and determining appropriate treatment options.
