California Hearing and Balance Audiology Center on Chula Vista's Third Avenue provides comprehensive audiological testing and hearing aid fitting within the Third Avenue Village medical corridor. The clinic's vestibular assessment protocol identifies benign paroxysmal positional vertigo and other balance disorders that frequently require coordinated rehabilitation through Spine & Sport Physical Therapy's vestibular therapy program. Operating as part of the California Head & Neck Specialists network with additional locations in Carlsbad, San Diego, and Murrieta, the Chula Vista office at 577 Third Avenue anchors ENT and audiology services for western Chula Vista's 91910 ZIP code. Pediatric and geriatric hearing evaluations feed into the broader sensory health referral pathway that includes vision screening at H Street Optometry on the nearby H Street commercial node. The team of otolaryngologists and Doctors of Audiology treat conditions ranging from chronic otitis media to sensorineural hearing loss and tinnitus. Diagnostic capabilities include videonystagmography for vestibular function, tympanometry for middle ear compliance, and real-ear measurement verification during hearing aid programming to match prescribed gain targets within 2 dB tolerance.
