  1. Otoscopy
    Otoscopy is the process of using a device known as Ostoscope and magnifying glass to check the person’s ear with the help of a torch. This method provides the initial diagnosis and checks if anything has blocked the ear canal which has affected the hearing.
  2. Audiogram
    Audiogram is the hearing test. In this test, the patient is given headphones and different sounds of different intensity are played. The patient is provided with a response button which he has to press when he hears the sound; depending on his response the audiogram is plotted. This gives an idea of the degree of impairment the person is suffering from.
  3. Speech Audiometry
    This is a different form of Audiogram. In this test headphones are provided to the patients. Certain words are pronounced through an audio system which the patients need to hear and repeat the word. This test is used to detect the hearing loss in the patient.
  4. Tympanometry
    This test involves the ear drums and the parts associated with it. This test needs to be performed very carefully. A small rubber tip is inserted into the ear and the air pressure and sound is initialized in the patient ear. This is a small test and lasts only for 10-15 seconds. The patients experience different sensation in the ear. This test needs to be performed with utmost care to avoid any discomfort to the patient.
  5. Otoacoustic emission testing
    In this test a small foam based tip is inserted into the patient’s ear. The patient will feel a tickling sensation and some sounds will be generated. The patient need not react to these sounds and need to sit still for 30 seconds. This test measures normal hearing or impaired hearing.

This test can be conducted in open without any earphones or if the child is comfortable an earphone can be used. The thresholds are obtained and an audiogram is plotted which detects the child hearing status. This is a visual exercise as the child’s reaction is taken into account.
  2. Play Audiometry
    This test is performed for children above 2 years. Lot of toys are placed in front of the child. Earphones are fitted and different sounds are played. The child hears the sound and identifies the toys and plays with them. The hearing threshold are noted and plotted on the audiogram to detect the hearing status of the child.
