Introduction A high frequency hearing loss will affect a person’s ability to understand speech. People with high frequency hearing loss can hear vowels just fine, but they can’t hear are the consonants sounds. Aim & Objectives Objective of this study is to construct a high frequency word list in Kashmiri to determine the speech recognition score of individual with predominantly high frequency sensorineural hearing loss. One of prime objective of evaluation of a hearing impaired individual is to estimate speech perception deficits that he/she experiences in real life situations. High frequency word lists are one such tool useful in enumerating consonant perception deficits in hearing impaired. This method adopted to develop a standardized list of such words in Kashmiri. Method Participants A total of 64 individuals with normal hearing sensitivity took part in the study. Group I constituted 32 females and 32 males in Group II. The age range of the participants were from 18 years to 40 years. Procedure Study was conducted in two phases. A. Development of high frequency word list. Both bisyllabic and trisyllabic words were considered to develop the test. Approximately 180 words were scrutinized for the validation of the words. A three point rating scale was used to validate the items as appropriate, not appropriate and appropriate with modifications. A total of 6 Audiologists with an experience of more than three years of service in the audiological set up rated the same. Statistical analysis was done to profile the correlation among the ratings obtained. The 70 most familiar with a rating of appropriateness were assessed for the spectrum information using spectrographic analysis (Long Term Average Spectrum- LTASS) using Goldwave version 6.0 and Praat software. The 65 words that were available for the construction of high freuancy test were further categorized into a bisyllabic and a trisyllabic list. The Recording were done in a sound treated room were the noise levels were a per ANSI guidelines. Results and Discussion The developed test material was standardized by obtaining speech identification scores in 60 native speakers of Kashmiri. SRT was estimated through bracketing procedure using standardized Kashmiri words. Each correct response was given a score of one and incorrect response was given a score of zero. Repeated measures of Analysis of Variance was carried out to test the statistical significance. Psychometric function of the word lists were measured by obtaining the WRS at different intensities. Around 50% of the subjects did obtain Max WRS Scores by 30 dB SL (ref. SRT). The variability of scores is also minimum at 40 dB SL, suggesting that the lists are inherently uniform to obtain WRS. All subjects obtained 0% scores at 15 dB SL (ref: SRT), in the present study. AS PTA average and SRT average was 15- 20 dB for most subjects and was a norm PTA-SRT agreement. Conclusion The present study focused on development of high frequency word list in Kashmiri and standardization of the word list in normal hearing Kashmiri Speakers. The Word Recognition score at 40dBSL was obtained for 64 normal hearing individuals and the results shows all individuals obtained score more than99%. However, the developed test to be administered on individuals with high frequency hearing loss.
