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.
Some techniques used are testing speech awareness thresholds to get the lowest level at which speech can be heard at least 50 percent of the time. Spondaic words are used as they have equal emphasis on each syllable, are easily understood, and contain information in each syllable that allow reasonable accurate guesses. It is a great test for younger patients, those who speak another language, or those who have neurological damage.
The speech recognition threshold test measures recognition of speech at the lowest level 50 percent of the time and it also uses spondaic words. The softest level words recognized and repeated are tested for, this also offers a pure-tone threshold. Gain can be measured during the selection of hearing aids.
Suprathreshold word-recognition testing estimates the ability to understand and repeat conversational single-syllable words, it is also called word or speech discrimination testing. The words used are phonetically balanced, they are presented by a live person, a CD, or a tape. The patient repeats the words to the audiologist and each correct word is give a 2 percent score. When 80 percent or better is achieved the test is stopped, if lower than this it is continued. This test is also performed with patients wearing their hearing aids to check improvement.
Very young children present another challenge for testing as they have limited language skills, picture cards representing spondaic words can be used. Prior to testing the child must understand what the card represents. There is a list of words specifically selected for children in kindergarten and first grade levels.
The word intelligibility test asks children to identify pictures by pointing to them, they are given 25 pages of color pictures each representing a single syllable word. This test is great for for children who are hearing impaired and are 4 years old and up. For children 3 and up the the Northwestern University speech test is a great option. Using both words and sentences, the pediatric speech intelligibility test is for children 3 and up.
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.
