Hearing tests are auditory checks used by doctors to assess and determine the hearing ability of young children. The type of test to use usually depends on the age of the child, for example, hearing tests for young children are different from hearing tests for newborn babies. Moreover, some hearing tests are also based on the level of understanding of the child (Dunlap, 2009). Different tests can be performed to evaluate the hearing ability of young children. The most common hearing tests for young children are pure tone audiometry and tympanometry tests.

In pure tone audiometry tests, the doctor uses a special kind of electrical machine that produces sounds at various levels and pitches. During the test, the child puts on special earphones and he or she is requested to respond in some way when the tone or sound produced by the electrical machine is heard through the earphone. According to Dunlap (2009), this method of testing hearing might be unproductive if the child does not cooperate effectively.

Tympanometry is a hearing test carried out by physicians to determine the functionality of the middle ear of a child. According to Gargiulo and Kilgo (2010), tympanometry tests do not tell whether or not the child hears or can sense sounds and pitches but assists in identifying changes in pressure in the middle ear. During a tympanometry test, the child should be still and should not be engaged in any activity such as talking or movements.

On the other hand, vision screening tests are carried out to evaluate the ability of the child to see clearly. Vision screening tests are performed to establish various eye problems such as strabismus, myopia, hypermetropia and reduced vision. The red reflex test is performed to verify if the child suffers from cataracts or retinoblastoma, eye alignment tests are conducted to check for strabismus whereas unilateral cover tests are conducted to find out the ability of the child to follow an object with one eye closed.
