There is lack of questionnaire in Hindi and this work will help a lot in future. The English THI was translated to Hindi by person expert in both English and Hindi. The translated THI was given to 40 people with Hindi as mother tongue for rechecking the words. The final THI (Hindi) was used in assessment of severity in 100 tinnitus patient.
