Hashir Aazh

Hashir Aazh, PhD is Director of Hashir International Institute and an academic clinician specialising in tinnitus, hyperacusis, misophonia, and other forms of sound sensitivity. Over the last decade, he has trained and supervised more than a thousand audiologists, psychologists, and other healthcare professionals through specialist masterclasses and professional development programmes focused on tinnitus and sound intolerance.

He has authored more than 70 peer-reviewed publications in audiology and hearing sciences, alongside numerous book chapters, invited articles, and professional publications. He has played a leading role in advancing audiologist-delivered cognitive behavioural therapy (CBT) for tinnitus, hyperacusis, and misophonia through clinical innovation, professional training, and research. His work has contributed to the development of assessment frameworks, psychometric instruments, and clinical pathways designed to improve the evaluation and management of tinnitus and sound intolerance.

His research has contributed to the assessment of symptom severity using measures such as the Sound Sensitivity Symptoms Questionnaire (SSSQ) and the average uncomfortable loudness level in the more sensitive ear (ULLmin). He has also contributed to the development of impact measures, including the Tinnitus Impact Questionnaire (TIQ), Hyperacusis Impact Questionnaire (HIQ), Misophonia Impact Questionnaire (MIQ), and Noise Sensitivity Impact Questionnaire (NIQ), as well as measures of patient confidence in managing tinnitus and sound intolerance through the 4C questionnaires for tinnitus, hyperacusis, and misophonia.

In addition, he has led research on internet-based cognitive behavioural therapy (iCBT) interventions and on adapting audiological procedures to better meet the needs of people with tinnitus and hyperacusis. His work has included the development of audiological diagnostic criteria for hyperacusis and screening tools to support the identification of psychological comorbidities and decision-making regarding referral to mental health services, including the Screen for Anxiety and Depression in Tinnitus (SAD-T).

As Director of Hashir International Institute, he leads initiatives in clinical research, professional education, service development, and international collaboration. He serves as President of the 8th International Conference on Hyperacusis and Misophonia, to be held in Hanover, Germany, in October 2026, and President of the 4th World Tinnitus Congress and XV International Tinnitus Seminar, to be held in London, United Kingdom, in 2027. He is also the founder of the International Conference on Pharmacology and Gene Therapy for Tinnitus and the International Seminar on Emotional and Sensory Experiences in Children with Autism Spectrum Disorder.

Dr Aazh is co-author, with Brian C. J. Moore, of Living Well with Tinnitus: A Self-Help Guide Using Cognitive Behavioural Therapy (2022), which translates evidence-based cognitive behavioural principles and contemporary tinnitus science into practical strategies for people living with tinnitus. The book forms part of the Living Well series of self-help guides and has been widely used by patients and healthcare professionals interested in tinnitus self-management.

He has also served as Guest Editor for several scientific journals, including the International Journal of Audiology, Journal of Hearing Science, Noise & Health, Brain Sciences, and Audiology Research. Through Hashir International Institute, he continues to promote evidence-based approaches to tinnitus and sound intolerance care, professional training, and scientific collaboration. His work is guided by a commitment to research, education, and international partnership, aiming to improve the lives of people affected by tinnitus and sound intolerance while advancing standards of care worldwide.
