Which method is primarily used in objective audiometric testing?

Pure tone audiometry is considered the primary method for objective audiometric testing because it measures an individual's hearing sensitivity across various frequencies using controlled tones. This method allows audiologists to obtain quantifiable data on the patient's ability to perceive sounds at different pitches, leading to a clear understanding of their hearing capabilities.

In contrast, self-assessment questionnaires and aural rehabilitation interviews rely on subjective responses from the patient, which can introduce biases and vary from person to person. While they have their place in assessing hearing-related issues, they do not provide the objective, quantifiable measurements that pure tone audiometry does. Similarly, speech perception tests assess how well a person can understand speech sounds but may also be influenced by varying factors such as familiarity with language or context, making them less purely objective compared to pure tone audiometry.

Thus, pure tone audiometry stands out as the primary objective method employed in audiometric testing.
