Circadian rhythm is common for all living organisms and nearly all physiological functions, especially sleep-wake cycles, exhibit circadian rhythmicity. A short survey conducted in the study center revealed that majority of the tinnitus subjects reported a difference in tinnitus severity across the day. So the current study focused on finding out the influence of circadian rhythm on tinnitus severity. Materials & Methods: Study was conducted on 20 tinnitus subjects irrespective of age, gender, hearing status and type of tinnitus. Kannada version of MEQ was given to all the subjects to classify them to various circadian types. A visual analog scale was also given to rate the severity of the tinnitus in the morning and evening. Results: The result of the current study states that, there was a significant difference in the tinnitus severity for moderate morning type individuals in the morning and evening and not for the intermediate group. Conclusion: So we can conclude that, circadian rhythm has a strong association with the severity of the tinnitus.

According to a survey conducted by USA, 40 million people are affected by tinnitus. Objectives: India being a multilingual country needs to develop and standardize THI in Indian languages. The present study concentrates on Developing and Standardizing THI in Kannada. Materials and Methods: Questions from English version of THI were translated and modified by two professionals who have a degree of MA Kannada. Translated inventory was given to 50 native Kannada speakers for the familiarity check & the most familiar sentences were included in the study. Tinnitus questionnaire was then administered, followed by the Kannada version of THI on 140 patients and total scores were obtained. Results: Analysis revealed 14% of the patients fall under the category of Slight, 38% under Mild, 26% under Moderate, 16% under Severe and 6% under Catastrophic group. An item total correlation and Cronbach-alpha test was administered to examine the reliability measures and the scores were 0.883 and 0.885 on standardized item. Conclusion: Scores of Cronbach-alpha test shows that Kannada version of THI is a standard and reliable tool for measuring the handicap caused by tinnitus and can successfully classify individuals on a severity basis.
