20. Estimates an individual’s maximum (best) ability to understand speech.
A. Speech awareness threshold (SAT)
B. Speech recongnition threshold (SRT)
C. Word recognition score
D. Most confortable loadness level (MCL)
C. Word recognition score (WRS)
Word recognition score represents the patient’s best ability to understand speech. It is a percentage score, not a single loudness value (like SRT or MCL).
Remember, the loudness level of WRS testing is based upon the patient’s SRT. If we present the sound at 40 dB above the SRT (the most common value used), it should be loud enough for the patient to hear well, because that is 40 dB above the level at which they are first able to identify words.
E.G. Mr. Smith, you do have a hearing loss. However, we know based on the test we did when the words were loud enough for you that you got 100 % of them right. This means that if we can turn sounds up for you, with something like a hearing aid, you will probably do quite well.
