Objective Hearing & Brainstem Mapping
A BERA (Brainstem Auditory Evoked Response Audiometry) test, also known as a **BAER test**, is an advanced, fully objective electrophysiological technique used to observe how sound signals travel from the inner ear down to the brainstem control centers. Since this evaluation collects responses straight from the central auditory nerve pathways, it demands zero active response tracking from the patient.
At Total Diagnostic Center in Freeganj, Ujjain, BERA serves as a cornerstone tool for early newborn screening and identifying deep-seated hearing threshold issues in young infants or individuals who cannot undergo standard subjective audiology charting safely.
Essential Clinical Applications
This screening assists physicians in diagnosing structural auditory processing speeds, pinpointing infant sensorineural hearing loss thresholds, ruling out lesions along the eighth cranial nerve, and tracking otoacoustic nerve conductivity benchmarks cleanly.
Brainstem Auditory Evoked Wave Response
Typical charting shows Peaks I-V. **Wave V** acts as the crucial reference used to pinpoint true hearing thresholds down to decibel variances.
Anatomical Wave Origins
The recorded wave peaks represent structural signal transitions through the nervous system:
Preparation Rules
- Clean Scalp & Forehead: Wash the patient's hair and skin area properly before entering the center. Eliminate styling creams, natural oils, or hair products so sensor patches attach easily.
- Sedation & Natural Sleep: For very small infants, testing is easiest while they are asleep. Parents are requested to keep infants awake for a few hours before the slot, feeding them right before testing to induce natural sleep.
- No Active Illness: Fluid accumulations inside the ear canals due to cold, cough, or severe ear infections can alter sound conduction paths. Ensure the ears are clear on the test date.
Note for Parents Regarding Pediatric BERA
Please rest assured that the BERA test is completely safe, painless, and carries absolutely no radiation risks. The click sounds delivered via the special soft tip insertion earphones are comfortable and tailored to normal safety levels. Parents are encouraged to stay in the lab alongside the child throughout the recording timeline.
