A test which measures the speech discrimination (word recognition) conducted by transmitting a list of words to the patient, via digital CD-reader, through earphones or bone vibrator; the test is carried out using the same device used for the pure-tone audiometry test; lists containing 10 words are presented to the patient while the audiologist records the intensity at which the patient is able to correctly repeat all the words.
This test is usually conducted for children 7 months to 2 1/2 years.
The child sits on a parent’s lap or in a chair between two calibrated loudspeakers (or headphones can be used). When a sound is made, an infant’s eye-shift or head-turn response is made toward the sound source.
This process is repeated using different intensity levels and at different frequencies in order to discover the child’s hearing thresholds at different hearing frequencies.
In this test, the child raises his/her hand or presses a button upon hearing a tone through the headphones.
The objective of this test is to obtain the hearing thresholds at different frequencies for each ear. This is in addition to obtaining the thresholds of air and bone conduction.
Conditioned Play Audiometry
This test is usually done for children 2 1/2 to 5 years. In this test, the child wears headphones and is shown how to perform a repetitive play task – for example putting a cube in a box when a sound is heard.
The objective is to obtain thresholds of air and bone conduction.
