It is important to use appropriate testing materials for the different langage developmental levels according to the age. As the Korean monosyllabic word lists for the children were not standardized properly, the purpose of this study was to develop the Korean standard monosyllabic word lists for school aged children and preschoolers (KS-MWL-S & KS-MWL-P). Considering the criteria given by the literatures such as phonetic balance and equal range of phonetic composition of speech, words in common usage, and words’ familiarity, etc, first 1,739 & 1,351 monosyllabic words were selected for candidates of KS-MWL-S & P. Those were extracted from the conventional lists, the first and second graded familiar words, the words that were included in the dictionary, children’s books, published articles, and children’s TV program. In order to reflect the actual frequencies of syllable in general colloquialism, initial and final consonants’ and vowels’ frequencies in everyday dialogue were investigated and controlled. The KS-MWL-S & P were developed with selected final 100 monosyllabic words, respectively, followed by examinations of psychometric functions and homogeneity of the stimulus and corrections referred by the experts. The psychometric function tests were performed with the identical method with the KSMWL-A development. The subjects were 30 children (mean age:9.23) for the school aged children’s list and 8 children (mean age: 5.75) for the preschoolers’ list. The mean slopes were 6.49 and 3.07 and the words that were within 1.00 standard deviations of the slope and the level were only included. Picture recognition tests were also performed to 3-4 years old 91 children for verification of the pictures that are drawn by the professional illustrators followed by the corrections. The KS-MWL-S & P 100 words were composed of conventional word lists by Hahm (1962) with 67% (67 words) for the school aged children’s list and 68% (68 words) for the preschoolers’ list, the first and second graded familiarity words with 98% (98 words) for both lists. Also, consonant-vowelconsonant formation was mostly composed with 60% (60 words) for the school aged children’s list and 71% (71 words) for t","PeriodicalId":30299,"journal":{"name":"Audiology","volume":"4 1","pages":"141-160"},"PeriodicalIF":0.0,"publicationDate":"2008-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68458312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sentence lists for each age group were 8 lists where each list was consisted of 10 sentences that included 40 key words. These sentences were selected based on the selection criteria for vocabulary and sentence structures of CID Everyday Sentence Test, and the naturalness and familiarity of the sentences were verified through the Sentence Naturalness Test. The degree of difficulty for each sentence list was made to vary evenly through the analysis of vocabulary, sentence structure, phoneme composition, frequency characteristics and psychometric function. The equivalency of degree of difficulty among the lists was proven by the insignificant difference in the frequency characteristics and psychometric function analysis among the lists of each age group. Moreover, since the lists were produced into CD sound source, they would be able to complement various problems from the use of live voice during the test. We highly expect these sentence lists to be used effectively as a useful testing battery for evaluating listening skills of everyday life in a clinical setting.","PeriodicalId":30299,"journal":{"name":"Audiology","volume":"4 1","pages":"161-177"},"PeriodicalIF":0.0,"publicationDate":"2008-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68458490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The two goals of this study were:1) to determine the coupler gains preferred by hearing-impaired listeners as a function of the input level;and 2) to compare the Korean preferred coupler gains with the coupler gains from NAL-NL1 that are based on English speech sounds. Eighteen hearing-impaired listeners (10 females and 8 males) with sensorineural hearing loss served as subjects. The ages of the subjects ranged from 47 to 88 years (M=67.9 yr, SD=8.7 yr) and their pure tone averaged (PTA) thresholds among 500, 1,000, 2,000, 4,000 Hz were between 42.5 and 75.0 dB HL. To avoid no preference for hearing-aids gains, the preferred coupler gains were examined at least after the three times of hearing-aids adjustments. The preferred coupler gains were measured at the frequencies between 250 and 4,000 Hz, with the conversational level sounds. Results showed that the Korean preferred coupler gains were lower than the coupler gains transferred from the fitting formulas of NAL-NL1, with greater differences in the frequencies below 1,500 Hz. These differences should be considered when fitting the hearing aid for the Korean hearing-impaired.","PeriodicalId":30299,"journal":{"name":"Audiology","volume":"4 1","pages":"69-73"},"PeriodicalIF":0.0,"publicationDate":"2008-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68458340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Frequency pattern test has been used to measure central auditory function that is sensitive to lesions in either hemisphere or interhemisphere. A wealth of experimental evidence suggests that frequency pattern recognition degrades with aging, and that performance deficits are more severe in verbal than in humming modes of responses Bellis & Wilber, 2001 . Frequency pattern test consists of 60 patterns of three-tone burst in varying patterns of high1,122 Hz and low880 Hz frequency. Thirty items were presented to each ear, with the listener humming or verbally labeling the patterns. Twenty subjects were between the age of 20 29 years and 10 subjects were between the ages of 60 70 years all with normal hearing sensitivities. For both the humming and labeling conditions, mean scores of elderly subjects were significantly lower than those of young subjects. The average scores of young subjects were 99.49% for the right and 99.67% for the left for humming. Scores for labeling were 93.99% for the right and 93.99% for the left. Elderly subjects scores were 79.67% for the right and 80.66% for the left ear for humming. The scores for labeling were 47.33% for the right and 44.66% for the left. The results for the population in Korea identified a pattern that shows that the pattern recognition abilities are degraded by aging.

This is thought to be due to the inhibitory control that the medial olivo-cochlear bundle (MOCB) exerts on the outer hair cell function. The purpose of this study was to investigate effects of contralateral stimulus on TEOAE. Contralateral suppression of TEOAE using four types of stimulus was measured in 30 young adults (30 ears) with normal hearing at 30, 40, 50 dBSPL. Contralateral stimuli were broad band noise (BBN), narrow band noise (NBN), amplitude modulation (AM) and frequency modulation (FM). This study showed that TEOAE suppression using contralateral noises increased orderly AM, FM, NBN and BBN at 40 and 50 dBSPL. Except for BBN, there was no significant difference between NBN, AM and FM. And as contralateral noise levels from 30 dBSPL to 50 dBSPL increase, TEOAE suppression also increased. But there was no the effect of gender. These results indicated that OAE represented a means of functional exploration of the active micro-mechanical properties of OHCs and our study was meaningful in the light of indicating amplitude fluctuation and frequency bandwidth effects in MOCB activation.","PeriodicalId":30299,"journal":{"name":"Audiology","volume":"2 1","pages":"160-164"},"PeriodicalIF":0.0,"publicationDate":"2006-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68457930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
