Speech reception thresholds for digits.

Of every 10 Canadians, 4 do not speak English as a first language. With non-native speakers of English, SRT testing using spondaic words lists, after the fashion in the U.S.A., may be difficult or invalid. This study examined the viability of using a closed set of English digits (1, 2, 4, 5, 9) for SRT testing in a Canadian setting. Ss were 130 consecutive patients referred for audiologic assessment in an English hospital in Montreal. Approximately 1/3 were native English, 1/3 native French, and 1/3 with other ethnic languages. Digit SRTs by a 10-db-down and 5-db-up procedure correlated very highly with both the standard 3-frequency (.5, 1, 2 kc/s) pure-tone average HTL (r = .94) and the Fletcher average of the 2 best speech-frequency pure-tone HTLs (r = .96). This study concluded that serial digits are viable SRT testing material for Canadian speech audiometry and should be studied for application to other multilingual populations.

Comparison of English and French versions of a dichotic auditory perception test (SSW) on normal bilingual subjects.

Young adult, normal-hearing, Canadian-French Ss (5 M, 5 F) from Montreal were matched for sex, age, and education with 10 Canadian-English Ss. Each S self-rated his receptive and expressive abilities in his non-native language. Then, all were given a new French and a standard English version of the SSW test. After controlling for second-language ability as a covariate, ANOVA showed performance significantly worse in the second language and in the dichotic condition. French Ss performed better on the non-dichotic condition of the English SSW than did English Ss on the French version. This study suggests that the new Canadian-French version of the SSW test is comparable in difficulty to the original English EC tape, but cautions against clinical use of SSW tasks with second-language Ss.

Phonetic factors in the dichotic alignment of the Staggered Spondaic Word Test.

The dichotic alignment of the competing monosyllables of the SSW EC tape was measured at 6 alignment reference points: word and sonorancy onset, center, and offset. Acoustic phonetic characteristics of the onsets and offsets of the competing monosyllables were also measured, including the durations of the pre- and post-sonorancy speech signal as well as binary codes for fricatives, nasals, plosives and liquids. Factor analysis of these variables suggested that the perceptual alignment process used with the EC tape may have indeed allowed phonetic variables to influence non-dichotic alignment.

False air-bone gap.

A single case is reported of a severely hearing-impaired child with a finding of a large air-bone gap on pure-tone audiometry on multiple tests. Exploratory surgery found normal middle ear function. Subsequent audiometry indicated the presence of a false air-bone gap resulting from vibrotactile responses. Test procedures for identifying vibrotactile responses are discussed.
