Discover the clinical importance of Pure Tone Audiometry (PTA), Tympanometry, and Brainstem Evoked Response Audiometry (BERA) for hearing loss.

Why Regular Hearing Evaluation is Vital

Hearing loss often progresses silently without pain. Early computerized evaluation is essential to differentiate between conductive hearing loss (treatable surgically) and sensorineural hearing loss (managed with digital hearing aids).

Diagnostic Audiology Services at Vashu Hospital

  1. Pure Tone Audiometry (PTA): Conducted in a sound-isolated acoustic chamber to determine hearing threshold across multiple sound frequencies (250Hz to 8000Hz).
  2. Tympanometry: Evaluates middle ear pressure, eustachian tube function, and presence of fluid behind the eardrum.
  3. BERA / ABR Testing: Objective electrophysiological test that records brainstem response to auditory stimuli. Essential for screening newborns, infants, and suspected acoustic neuromas.

When Should You Get an Audiometry Test?

If you frequently ask people to repeat themselves, increase TV volume excessively, struggle in background noise, or experience persistent ear ringing (tinnitus), consult our ENT clinic for immediate evaluation.
