Word Recognition of Digit Triplets and Monosyllabic Words in Multitalker Babble by Listeners With Sensorineural Hearing Loss

Wilson, Richard, Burks, Christopher A., Weakley, Deborah G. 01 January 2006 (has links)
In an initial experiment (Wilson and Weakley, 2004), word recognition was assessed with six digit triplets presented at 14 signal-to-babble ratios (S/B) in 2 dB steps. An abbreviated version of the protocol was developed for clinic use involving three digit triplets at 7 S/Bs in 4 dB steps. The purpose of this experiment was to examine the relationship between the two digit protocols with comparisons made with other variables including age, pure-tone thresholds, subjective measures of understanding speech in quiet and in noise, and word recognition of monosyllabic words in quiet and in babble. Ninety-six listeners with sensorineural hearing loss participated. For equivalent performance, the short version of the digit triplets required (1) a 2.6 dB more favorable S/B than the long version and (2) a 15.1 dB less favorable S/B than the words. Age, hearing loss, and subjective evaluation of the ability to understand speech in quiet and in noise were not related to performance on digits or words in multitalker babble.
