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.
Audiometry is done in a testing room made up of 2 rooms, an equipment room and an evaluation room. The equipment room contains the audiometer, input devices such as microphones, tape recorders, and CD's for testing. Tests are performed using earphones and are sent to one or both of them. They can also be done through a bone-conductor vibrator. Materials can also be presented through loudspeakers in the sound-field.
There are various tests used to find out what a person's speech thresholds are, the lowest level that speech can be heard at is tested at a 50 percent awareness level. Words that have equal emphasis on the syllables, or spondaic words, are used because they contain information in each syllable that allows the patient to make a reasonably accurate guess and they are easy to understand. This type of testing is excellent for children, people with neurological problems, and those who speak a different language.
The speech recognition threshold test measures the lowest point at which language can be understood at least 50 percent of the time using spondaic words. The softest level of hearing and repeating is measured and it shows pure-tone thresholds. Appropriate gain is measured for proper hearing aid selection and settings.
The suprathreshold word recognition testing shows the ability to repeat and understand conversation using one syllable words, it is also known as speech or word discrimination testing. The words used are phonetically balanced and either a tape, CD, or a live person presents the test. The words are repeated by the patient to the audiologist with each correct answer receiving 2 points. When an 80 percent score is achieved the test is over, otherwise it will continue. Patients wearing their hearing aids also take this test to check improvement in their hearing.
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.
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.
There are other tests used for children such as the Bamford-Kowal-Bench speech in noise testing, phonetically balanced kindergarten testing, and the pediatric speech intelligibility tests. Early testing can insure little loss in academic achievement and social development. Finding a good audiologist will ensure the best results and accurate testing. Audiometers provide this critical information.
