Impedance Audiometry & Tympanometry

Impedance audiometry is an objective method based on the measurement of the pressure in the middle ear, stapedius reflexes, and tension of the tympanic membrane via Tympanometry. It is one of the most common and most accurate methods for testing the middle ear by Hearing Experts at Aanvii Hearing.

Impedance Audiometry & Tympanometry

The tympanometry test measures how the eardrum moves as air pressure in the ear canal changes, and plots the result on a graph called a tympanogram. At Muskan Speech & Hearing Centre, audiologists use this middle ear test for children and adults. It needs no response from the person, so it works well for babies too.
How is the eardrum test done?

• A soft probe tip is placed at the entrance of the ear canal.
  
• Air pressure is changed gently while a tone is played.
  
• The device records how the eardrum responds.
  
• Acoustic reflex testing may follow to see how the middle ear muscle reacts to loud sound.
  

• A blocked or full feeling in the ear
  
• Repeated ear infections
  
• Sudden or fluctuating hearing loss
  
• Ear pain after a cold or flight
  
• A child who seems inattentive or slow to respond to sound
