Types Of Hearing Test Etobicoke

Babies that have just been born will need to be screened to determine if their ears are okay or if there are any potential problems. This is done through two tests. One is the automated oto-acoustic emissions test, referred to in short as AOAE. It takes a short time and can even be performed while the baby is asleep. A very small earpiece is placed in the ears and then clicking sounds played through it. It is a hearing test Etobicoke residents may use on newborns.

For the test, in the event that the ears are functioning well, echoes will be produced in the part of the ear known as the cochlea. The sounds that result are sent to a computer for analysis. If the results are not clear enough, the test would have to be done once again or a different test performed. Failure of the first test may be attributed to unsettled state of the baby during the test, temporary ear blockage or presence of background noise.

The AABR test, known as automated auditory brain-stem response test involves placement of three minute sensors at the neck and head of the baby. Thereafter, headphones get placed over the ears then quiet sounds get played. Just like in most of the methods, the sounds are analyzed by the computer. The first two tests would not be ideal for older babies. There are special tests for them.

In visual reinforcement audiometry, a baby will be made to sit on the laps as sounds are played to them from a speaker. If the baby turns in the direction of the produced sound, a reward is given in the form of for instance a toy that is lit. In order to know the least sound the baby is able to hear at each pitch, the loudness will be varied. The same test may be performed using earphones. Earphones enable every ear to be tested on its own. It is used in kids between six months and three years old.

For the case of pure tone audiometry, an audiometer is used to generate sounds at varying volumes. The sounds that are played via headphones as the kid is told to show some response whenever the sounds are heard. The response can be for example pressing some button. Through reduction of sound level, the least sounds that can be heard by the child will be worked out.

The method is useful only for children above 3 years of age. It comes in handy for screening how well the hearing of a child is before school begins. There also is play audiometry in which the child is expected to perform some simple task whenever they hear sounds from headphones. Such a task include moving of a toy.

A speech perception test is very effective too. It assesses the ability of children to recognize words without observing the person make movements of the lips. The words are said directly to the child while ensuring no lip movements are shown or they are played through headphones. The child identifies a word through picking out a matching word or picture from a list.

The testing technique used will mostly depend on the age of a child. Hearing tests are also done on grownups. Adult testing techniques are different.
