Abstract

Study objectives: The objective of this study is to test the audiological balance between the lists in the 1-syllable and 2-syllable Word lists as well as to build the hearing threshold and normal speech discrimination index for children from 6 years old to 15 years old.  Study methodology: cross sectional study. Results: The monosyllabic word lists containing 10 lists, each list has 25 monosyllabic words; disyllabic word lists containing 10 lists, each list has 10 disyllabic words, all lists in each word lists are balanced in term of audiology and high reliability for test and re-test; SRT for normal hearing children from 6 to 15 years old is 14,4 ± 2,6dB; SDS for normal hearing children from 6 to 15 years old gets 0% at 0dB stimulation then increases when intensity louder and reach 100% at 35dB, SDS curve has its steep slope in the region of stimulation from 5dB to 25dB. Conclusions: The monosyllabic and disyllabic word lists are balanced in term of auditory reliability and its balances; normal data of SRT and SDS are usable to compare with hearing loss subjects.
