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.
Testing is done in a 2-room area, one is set up with the equipment and is sound-proof and the other is for the audiologist who is performing the testing. The equipment room has earphones, the audiometer, speakers, tape recorders, and CD's. The patient wears the earphones to participate in the testing, instruction is sent through one or both of them. A bone-conductor vibrator is also sometimes used. Loudspeakers are also used to present material into the sound field.
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 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.
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.
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.
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.
