The 20th Tinnitus Research Initiative Conference brought the international tinnitus community to Charité – Universitätsmedizin Berlin from 16 to 18 September 2026. Under the presidency of Professor Birgit Mazurek, the meeting presented a broad view of a field extending from laboratory mechanisms to clinical care and the lived experience of tinnitus.

The TRI 2026 abstract book contains 116 contributions, comprising 73 oral and 43 poster presentations, with submitters from more than 20 countries across five continents.

One of the clearest messages from Berlin was that tinnitus cannot be understood as a single, uniform condition. Researchers explored different phenotypes, comorbidities and treatment trajectories through audiology, neuroimaging, electrophysiology, psychological assessment, biomarkers and machine learning. This growing emphasis on subgrouping may help move the field towards more personalised and clinically meaningful care.

Hyperacusis also received considerable attention. Studies examined the limited agreement between questionnaires and uncomfortable loudness levels, the multidimensional nature of sound sensitivity, and possible mechanisms underlying pain hyperacusis or noxacusis. These presentations reinforced the need to distinguish carefully between different forms of reduced sound tolerance.

The clinical programme reflected a similarly wide range of approaches, including cognitive behavioural therapy, hearing interventions, cochlear implantation, pharmacological treatments, brain stimulation and multidisciplinary rehabilitation. Several studies highlighted the importance of mental health, stress, attention, sleep and comorbid health conditions. Together, they showed that treatment outcomes cannot be judged solely through changes in tinnitus loudness.

Basic and translational research remained strongly represented through studies of auditory pathways, inflammation, neural networks, somatosensory influences and autonomic responses. The philosophical symposium, The Tinnitus Trilogy, widened the discussion further by examining tinnitus through predictive processing, phenomenology and epistemology. It asked not only how tinnitus arises, but what it means to experience it and how we know that it is present.

Berlin demonstrated a field rich in methods, ideas and emerging interventions. It also highlighted the continuing need to connect mechanisms with the individual person, laboratory discoveries with clinical practice, and scientific progress with global access to care.

This conversation will continue at the 4th World Tinnitus Congress and 15th International Tinnitus Seminar in London, from 30 June to 2 July 2027, under the theme: From Mechanism to Meaning: The ABC of Tinnitus.
