This study aims to obtain the performance-intensity function in patients diagnosed with Ménière's disease. In addition, according to the stage of the disease, qualify through the Dizziness Handicap Inventory (DHI) and Tinnitus Handicap Inventory (THI) questionnaires the self-reported quality of life in the presence of tinnitus and vertigo. Ménière's disease affects the inner ear, which is composed of the cochlea and semicircular canals. Symptoms include severe disabling vertigo, nausea, vomiting, a feeling of fullness in the ear and hearing loss. Hearing loss is characterized as sensorineural, in which speech discrimination and intelligibility are altered, being quantified through the Speech Audiometry. Thus, in this work, the search for the performance-intensity function will be necessary data to understand and relate the different characteristic phases of the disease with speech intelligibility. Hypothesis: Patients with different audiometric configurations have specific speech audiometry curves that assist in determining the stage of the disease.
