Pure-tone audiometry is the main hearing test used to identify hearing threshold levels of an individual, enabling determination of the degree, type and configuration of a hearing loss and thus providing a basis for diagnosis and management.


Otoacoustic Emissions Hearing tests are usually performed on newborn babies to detect deafness.2 The test can also partially estimate hearing sensitivity and test for functional hearing loss. Functional hearing loss is also sometimes referred to as non-organic hearing loss and is a condition where you have symptoms or behaviors of hearing loss but there is nothing actually wrong with your hearing.


The brainstem evoked response audiometry (BERA) is an objective neurophysiological method for the evaluation of the hearing threshold and diagnosing retrocochlear lesions.The auditory brainstem response (ABR) test tells us how the inner ear, called the cochlea, and the brain pathways for hearing are working. You may also hear it called an auditory evoked potential (AEP). The test is used with children or others who cannot complete a typical hearing screening.


is a relatively new vestibular function test performed by stimulating one ear with repetitive pulse or click sound stimulation and then measuring surface EMG responses over selected muscles averaging the reaction of the muscle electrical activity associated with each sound click or pulse.


Electrocochleography (ECochG) is a measurement of stimulus-related electrical potentials, which include the cochlear micro phonics (CM), summating potentials (SP), and compound action potentials (AP) of the auditory nerve. This is an ideal test for the diagnosis of Meniere's disease


Impedance or immitance audiometry or Tympanometry is an objective test and the results of the test help in the understanding of the following parameters:

  • The status of the eardrum and the middle ear.
  • Functioning of the reflex pathways of hearing, involving the facial nerve, vestibulocochlear nerve and the auditory brainstem.
  • The three tiny bones of the middle ear.
  • Eustachian tube function.
  • The two muscles of the middle ear – tensor tympani and the stapedius muscle.
  • Functioning of the cochlea.
