Audiometers are invaluable in the testing of hearing loss. They allow the audiologist to determine the degree and the type of loss a patient has as well as their discomfort and tolerance to speech stimuli and their ability to recognize words. Information gathered helps in the determination of amplification devices and the proper hearing aids to prescribe.
The testing room that is used with an audiometer is split into two, one is a sound-proof room for the patient and the other is where the audiologist sits. In the evaluation room are speakers, earphones, CD's, tape recorders, and the audiometer. Using earphones, various tests are sent through one or both of them to measure levels of speech that can be understood. Some testing is done using a bone-conductor vibrator.
Speech awareness thresholds are tested to find the lowest point at which speech can be recognized half of the time. Words that have equal emphasis on each syllable are used, they are known as spondaic words and contain information in each syllable and are easy to understand so that there can be a chance of a reasonable guess. This type of test is good for young patients, those who have suffered neurological damage, and those who speak another language.
Speech recognition threshold measures the lowest level at which speech can be recognized at least half of the time. Spondaic words are used for this test as well. It determines the softest level that words can be heard and repeated and it validates pure-tone thresholds. It measures appropriate gain during hearing aid selection.
To estimate the ability of understanding and repeating conversation of single syllable words, the suprathreshold word-recognition test is used. This test is also referred to as speech or word discrimination testing. Phonetically balanced words are used and presented by CD, tape, or live and are repeated by the patient. A 2 percent score is given for each correct response and is stopped at 80 percent or continued if needed. Patients can be tested with their hearing aids to show improvement.
Testing young children is a bit more difficult and different methods need to be used to get the data required to correct their hearing losses. With limited language skills, picture cards of spondaic words are used. Children will be asked if they understand the pictures prior to testing. These are used for children in kindergarten and first grades.
One test that is often used is the word intelligibility test, it is comprised of 25 pages filled with colored pictures representing something named by single syllable words. This test is wonderful for children who are hearing impaired ages 4 and up. The pediatric speech intelligibility test uses a combination of single syllable words and sentences and is a good fit for those 3 and up. Another good test is the Northwestern University speech test that is good for ages 3 and over.
Other testing used for children include the pediatric speech intelligibility test, the phonetically balanced kindergarten test, and the Bamford-Kowal-Bench speech in noise test. It is best to find out early that a child has a hearing loss so they can have it corrected with hearing aids and speech therapy which will enable them to do well socially and in school. Audiometers are great machines to help determine what kind of assistance is best with the help of a talented audiologist.
