The idea is to find the lowest level at which identifiable two syllable
(spondaic) words can be correctly reproduced. If words that are not
recognizable are used, such as nonsense words, an element is added which does
not increase the accuracy of the test, but actually decreases its accuracy.

Generally it is not necessary with an intact auditory system to produce the
whole sentence. In cases of suspected central auditory involvement, such as a
problem in the brain, sentences are used. There are some who use a carrier
phrase with each discrimination word, such as "Say the word base, etc." This
does not necessarily add to the accuracy of the test, unless many words are
missed, then the audiologist should repeat the test with the carrier phrase. A
child who can score better than 88% without the sentence, does not likely have
a major central problem. I agree, however with your premise, that the real
world uses sentences, and that there is validity in a sentence approach with
kids. Its just not always strictly necessary.

True, however, ther is little likelihood of guessing, as there are thousands
of word possibilities in each list. The audiologist would be unlikely to give
the same list more than once. We mark on the form which particular list we
used for each test, so as to reduce the likelihood of this happening.

You raise a good point. Noise testing is very important in some cases. The
main reason we test in a sound proof booth is to find the level of hearing
which is unaffected by extraneous factors, such as noise. Some types of noise
can actually interfere with the test, when there is no pathology present in
the patient. In order to be certain of the maximum hearing status, without
unfair biases from other factors, booths are used. I see many kids who fail
school screenings, but have normal hearing, because they were distracted by
other children, or lights, etc. A good audiologist will also test for hearing
in noise when that is indicated or requested.
