Journal of International Advanced Otology requires and encourages the authors and the individuals involved in the evaluation process of submitted manuscripts to disclose any existing or potential conflicts of interests, including financial, consultant, and institutional, that might lead to potential bias or a conflict of interest. Any financial grants or other support received for a submitted study from individuals or institutions should be disclosed to the Editorial Board. To disclose a potential conflict of interest, the ICMJE Potential Conflict of Interest Disclosure Form should be filled in and submitted by all contributing authors. Cases of a potential conflict of interest of the editors, authors, or reviewers are resolved by the journal's Editorial Board within the scope of COPE and ICMJE guidelines.

Background:The present study aimed to develop and standardize a phonemically balanced bisyllabic word test in Tamil for adult listeners. Material and methods:In total, 1015 bisyllabic Tamil words were collected from different sources; 20 Tamil speakers rated the words for familiarity and 5 experts validated the content. Based on the familiarity rating and content validation, 760 words were shortlisted for phonemic balancing. Then 25 phonemically-balanced lists were prepared with 25 words in each. The prepared lists were presented to 100 normal-hearing listeners at 40 dB SL in quiet, and 30 listeners in noise at −5 dB SNR for the standardization process. The lists were also presented at different sensation levels (SLs) in quiet to 30 listeners to obtain a psychometric function. Results:The mean speech identification scores (SISs) in adults was 99.8% in quiet. The results revealed no significant difference in SIS across the 25 word lists, indicative of list equivalency. The scores increased as the level increased from 10 to 40 dB SL for all the lists, suggesting homogeneity in difficulty and audibility. However, in noise, only 23 lists were equivalent to each other. Conclusions:All the test lists can be utilized for testing during audiological evaluation in quiet, and 23 word lists are useful in noise.
