What does the O represent on an audiogram?

On an audiogram, the symbol "O" represents the response of the right ear. This symbol is part of the standardized notation used in audiological assessments, where specific letters are designated to indicate responses from each ear. The use of "O" for the right ear is widely accepted and helps professionals quickly interpret the results of hearing tests.

Understanding this notation is crucial for anyone working with audiograms, as it allows for the comparison of hearing levels between the right and left ears, which is important for diagnosing and treating various hearing conditions. Proper identification of these symbols ensures accurate communication of hearing capabilities, leading to appropriate interventions when necessary.
