Evaluation of auditory function (otoscopy, immittance testing—tympanometry to identify type “A” tympanometric curve, conventional pure-tone audiometry, and high-frequency audiometry)
Tinnitus assessment (acuphenometry—to identify psychoacoustic measures of tinnitus, assist in perceptual evaluation, and contribute to treatment, including identification of tinnitus sound type and an
