Which symbol represents air conduction masked on an audiogram?

In audiograms, symbols are used to represent different types of hearing tests conducted. The symbol that is specifically used to represent air conduction masked is the square. Masking is a technique used in hearing tests to isolate the ear being tested from sounds heard in the opposite ear, ensuring that the results reflect the true hearing ability of the tested ear.

The use of the square for air conduction masked allows for clarity when interpreting results on an audiogram. This is particularly important when evaluating patients who may have asymmetrical hearing loss, ensuring that each ear's performance can be accurately measured without interference from the other ear.

Awareness of these symbols and their meanings is essential for hearing professionals, as it aids in effective communication of test results and appropriate treatment decisions. Understanding how to read and interpret an audiogram is a fundamental part of practice in audiology and hearing dispensing.
