ABSTRACT |
The purpose of this research was to investigate psychometric functions with monitored live voice and taped presentation of one syllable
words for hearing impaired adults. The psychometric functions were also examined with respect to the degree of hearing loss. The data
were obtained from 20 ears of hearing impaired adults aged between 37 and 88 (M=70.2 years). Their hearing thresholds ranged
from 40 dB HL to 90 dB HL (M=62.3 dB HL). The newly developed Korean word list, which was consisted of 50 one-syllable words,
was presented from 0 dB SL upto 40 dB SL or UCL with 10 dB. The results showed that there was no statistically significant difference
of word recognition scores between MLV and CD data (F(1,3)=1.235, p>0.05). However, meaningful differences were identified
between the groups with lower versus higher hearing sensitivity (F(1,3)=26.215, p<0.05) without a significant interaction effect
regarding the stimulus presentation level. In conclusion, this research suggests that one-syllable words may be presented either in MLV
or in CD to hearing impaired adults for the word recognition test. However, more data based on the standardized test procedures are
needed before the clinical utilization. |
