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.
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.
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.
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.
