Non-invasive audiologic and vestibular assessments
standardized, single-session test battery performed in a sound-treated clinical laboratory. Procedures include tympanometry, tympanometry with simple maneuvers (Valsalva/Toynbee) for Eustachian tube function, pure-tone audiometry, otoacoustic emission (OAE) testing, acoustic reflex thresholds, and cervical vestibular evoked myogenic potentials (cVEMP) with EMG monitoring for adequate sternocleidomastoid activation. Testing is non-invasive, takes \~60 minutes, and is conducted under routine clinical practice conditions. No investigational drugs, devices, or biospecimens are used.
