A new national initiative aimed at strengthening tinnitus research and clinical collaboration across India has officially been launched with the establishment of the Tinnitus Clinical and Research Network India (TCRN-India).

The network brings together clinicians, audiologists, and researchers from different regions of India who share a common interest in advancing the understanding and management of tinnitus. The initiative begins with a core founding group of ten members and is designed as an invite-based collaborative platform to promote high-quality tinnitus research and foster scientific exchange across institutions.

The creation of TCRN-India reflects a growing international movement towards developing regional tinnitus networks capable of addressing local research priorities while contributing to the global evidence base. The initiative aligns closely with the vision of the World Tinnitus Congress to support the development of sustainable tinnitus clinical and research collaborations across different geographical regions.

According to the network’s founding framework, TCRN-India aims to:

• Promote high-quality tinnitus research across India
• Facilitate mentorship and support for early-career researchers
• Conduct multicentric collaborative studies
• Work towards standardized assessment protocols
• Develop a shared tinnitus research database
• Enhance national and international research visibility

India’s growing role in tinnitus research further strengthens the significance of this initiative. According to The Annual Tinnitus Report (2026), published by the Hashir International Institute, India was among the ten most productive countries worldwide for tinnitus-related scientific publications in 2025, contributing 18 eligible studies and accounting for approximately 4% of the global tinnitus literature. The report highlighted India as an increasingly important contributor to international tinnitus research, reflecting the country’s expanding academic infrastructure, large and diverse patient population, and growing expertise in audiology and hearing sciences.

These strengths position India well for large-scale collaborative research initiatives. By connecting clinicians and researchers across institutions and regions, TCRN-India has the potential to accelerate knowledge generation, improve methodological consistency, and enhance the country’s visibility within the global tinnitus research community.

As its first major project, TCRN-India is already developing a multicentric epidemiological study examining tinnitus prevalence, clinical characteristics, and associated factors across multiple regions of India. Participating centres are currently seeking ethics approvals, and a common study protocol has been developed.

The proposed study will be conducted as a multicentric, cross-sectional epidemiological investigation across participating centres in India. Adult participants attending audiology, otolaryngology, and affiliated clinical services will be recruited using a common assessment framework. Data collection will include structured tinnitus-focused case histories, demographic information, tinnitus characteristics, severity measures, and relevant clinical variables. Routine audiological assessments may also be included where appropriate.

The study aims to generate one of the most comprehensive datasets on tinnitus collected in India to date. Data from all participating centres will be entered into a shared database and analysed centrally to examine the prevalence, clinical profile, and associated factors of tinnitus across different regions of the country.

Beyond research, the network plans to hold regular virtual meetings, develop standardized research protocols, provide mentorship in research methodology and publication, and establish ethical data-sharing mechanisms among participating centres. Expected outcomes during the first year include the initiation of multicentre studies, completion of a national-level dataset, collaborative publications, and the development of a framework for a future national tinnitus database.

Commenting on the launch of the network, Prashanth Prabhu, one of the founding members of TCRN-India, said:

“Tinnitus research in India has grown steadily over the past decade, but much of the work has been conducted in individual centres with limited opportunities for large-scale collaboration. TCRN-India was established to bring together clinicians, audiologists, and researchers who share a common interest in tinnitus and who wish to contribute to a stronger and more coordinated research ecosystem. Through collaborative studies, mentorship, and the development of shared research frameworks, we hope to generate evidence that is both scientifically robust and relevant to the Indian population. Our first multicentric epidemiological study is an important step towards building a national evidence base for tinnitus and creating opportunities for future collaborative research.”

Commenting on the development, Hashir Aazh, President of the World Tinnitus Congress, welcomed the launch of the network and highlighted the importance of regional collaborations in advancing tinnitus science worldwide.

“Progress in tinnitus research increasingly depends on collaboration. Networks such as TCRN-India provide an opportunity to bring together clinicians and researchers with shared interests, develop robust multicentre studies, and generate evidence that is directly relevant to local populations while contributing to the international knowledge base. The World Tinnitus Congress is committed to supporting the development of tinnitus clinical and research networks across different regions of the world, helping to strengthen international collaboration while recognising the unique needs and priorities of individual countries.”

The launch of TCRN-India represents an important milestone for tinnitus research in South Asia and provides a model for future regional collaborations. As the network develops, it is expected to strengthen research capacity, support early-career investigators, and facilitate the generation of high-quality evidence that can inform both clinical practice and public health policy.

The World Tinnitus Congress looks forward to supporting and highlighting similar initiatives around the world as part of its broader mission to strengthen the global tinnitus community and promote high-quality, internationally connected research.
