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.
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.
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.
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.
Some other options for children are the phonetically balanced kindergarten test, the pediatric speech intelligibility test, or the Bamford-Kowal-Bench speech in noise test. Early detection will ensure that both children and adults live a normal life, develop socially and academically and are able to communicate with others. A good audiologist makes all the difference when testing with audiometers.
