A major obstacle to developing better treatments for tinnitus is the lack of a test or measure that can objectively assess whether someone has tinnitus and how severe it is. Making tinnitus measurable allows researchers to more easily assess the effectiveness of new treatments and meet the expectations of regulators in order to get those treatments to market.We spoke with Mehrnaz Shoushtarian (PhD) from the Bionics Institute in Australia, who are working on an objective measure of tinnitus based on Functional near-infrared spectroscopy (fNIRS) and a machine learning program. They believe that their technique will not only be able to distinguish whether someone has tinnitus or not, but also how loud it is.We cover the technical ins and outs of the objective measure, the underlying theories the work is based on, the future commercialisation of the technique, and the ultimate impact the Bionics Institute is hoping for.Become a Tinnitus Talk Podcast Patron at https://moretinnitustalk.com for bonus content, video interviews, Ask an Expert series, and more!
