South Bay Hearing & Balance serves Chula Vista from 453 Fourth Avenue as an independent audiology practice within the Beltone Hearing Care Network, providing diagnostic hearing evaluations, hearing aid fitting, and vestibular balance assessments. Comprehensive audiologic workups identify sensorineural, conductive, and mixed hearing loss patterns, with otologic referrals coordinated through providers such as ENT Associates of San Diego - Chula Vista office when medical or surgical intervention is indicated. The practice holds authorized dealer status for Beltone, Starkey, and Signia hearing aid platforms, fitting rechargeable, custom-molded, and over-the-counter models calibrated to each patient's audiogram. Beyond amplification, the clinic delivers tinnitus retraining therapy using sound-masking protocols and vestibular balance assessments for patients reporting vertigo, disequilibrium, or fall-risk concerns. Primary care physicians across the South Bay — among them Mohammed Elsayed, MD - Oxford Care — routinely refer patients for baseline audiometric evaluation when age-related hearing changes are suspected during annual wellness visits. Diagnostic capabilities include pure-tone audiometry across 250 Hz to 8,000 Hz frequency ranges, speech recognition threshold testing, tympanometry for middle-ear pressure analysis, and videonystagmography for vestibular function assessment.
