Rated tinnitus loudness: VAS scores for tinnitus loudness Rated tinnitus loudness: VAS scores for tinnitus annoyance Tinnitus Severity: Tinnitus Handicap Index Matched tinnitus loudness: Loudness match re: 1kHz tone in the contralateral ear to tinnitus (unless subject has bilateral or unilateral profound hearing loss) Minimum Masking Level: MML with broad band noise in ipsilateral ear to tinnitus (unless subject has bilateral or unilateral profound hearing loss) The Prototype 2 of the Tinnitus Functional Index is a 30-question evaluation tool currently under development with funding from the Tinnitus Research Consortium through a multi-center study hosted by the OHRC. The TFI will serve as a secondary outcome measure of tinnitus severity in Phases II and III. Thus far in development, the TFI has demonstrated good reliability, validity and high sensitivity to measuring treatment-related changes in tinnitus severity (responsiveness). The TFI has not been published, but the investigators believe that it would be beneficial to this study and provide an opportunity to use the TFI in a new clinical setting.
