Introduction Ménière disease (MD) affects the inner ear, comprising the cochlea and semicircular canals. Symptoms include severe incapacitating vertigo, nausea, vomit, aural fullness, and sensorineural hearing loss - in which speech discrimination and intelligibility are impaired and can be quantified with speech audiometry. Objective To investigate the influence of the stimuli presentation level in speech audiometry and the quality of life in adults with and without a diagnosis of MD. Method Two groups were formed with nine individuals each - one with and the other without MD. The Speech Recognition Percentage Index was researched with stimuli presented above the self-reported comfort level or 5 dB below the discomfort level. Dizziness Handicap and Tinnitus Handicap Inventories were administered to individuals with tinnitus and vertigo complaints. Results Speech recognition was better in the study group with higher presentation levels, as 75% of the sample improved their performance. The presence of vertigo significantly impacted the quality of life of individuals in the study group. Conclusion Speech recognition improves with higher presentation levels. Also, MD impacts the quality of life, especially regarding limitations caused by vertigo.
