Her medical history was unremarkable except for well controlled hypertension, for which she was taking amlodipine. She also had no history of excessive noise exposure, no previous otological problems, and no family history of note.

The results of an ENT examination were unremarkable, with normal ear canals and tympanic membranes bilaterally. Tympanometry was also normal in both ears.
