In order to assess hearing loss, audiometers are used to determine the type and degree of the loss. This machine also shows the tolerance or discomfort to speech stimuli and offers information in the abilities of word recognition. The information from testing can help to determine correct hearing aids or other devices needed for patients with significant losses.
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.
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.
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.
A popular test for children is one where they identify cards by pointing to them. Word intelligibility testing consists of 25 pages of colored pictures that represent something named by a monosyllabic word. This test is used for children with hearing impairment and can be used for children ages 4 and older. The Northwestern University speech testing was developed for children 3 and older. Pediatric speech intelligibility testing uses both sentences and monosyllabic words where children point to the appropriate picture, this test is for children ages 3 and older.
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.
