A method includes:a first test including adjustment by the patient of the sound pressure level of an audio stimulus to a specified hearing perception level and selection of the corresponding sound pressure level, thereby generating a first test result corresponding to the value of the sound pressure level selected by the patienta second test including adjustment by the patient of the sound pressure level of the audio stimulus to the same specified hearing perception level and selection of the corresponding sound pressure level, thereby generating a second test result corresponding to the value of the adjusted sound pressure level selected by the patientcomparing the first test result and the second test result.The result of the test is accepted or rejected based on the closeness of the test results, and feedback is provided to the patient based on this closeness.
