Our Services

At Hashir International Institute, we help you with assessment and management of your misophonia, tinnitus or hyperacusis via private consultations with our specialists. Our main speciality is cognitive behavioural therapy (CBT) for misophonia, tinnitus and hyperacusis in children and adults.



Assessment is conducted by our senior audiologists who are specialists in misophonia, tinnitus, and hyperacusis rehabilitation. They will assess the type and severity of your symptoms, make a diagnosis, and develop a comprehensive treatment plan.


Psychological evaluation

Our clinical psychologists will explore if there are any underlying psychological/psychiatric conditions that might require separate treatment. This is different from the anxiety or stress symptoms related to the experience of tinnitus, hyperacusis, noise sensitivity and misophonia.



In educational sessions, our neuroscientists will discuss the latest scientific understanding about the mechanism of misophonia, tinnitus and hyperacusis and the research studies on treatment methods.


Occupational therapy (OT) evaluation

The aim of our OT sessions is to assess if you or your child have a broader sensory processing disorder, autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), neurodevelopmental disorders, and/or emotional regulation difficulties in addition to sensitivity to sound and/or tinnitus.


Health psychology evaluation

Our health psychologist will assess if there are any improvements and behaviour changes that you can achieve to cope well with misophonia, tinnitus and hyperacusis, and talk to you about how to maintain your physical and psychological health throughout the treatment process. Our health psychologists will help you to feel more confident and develop a more realistic belief about your misophonia, tinnitus and hyperacusis and its long-term management.


Cognitive behavioural therapy (CBT)

We are one of the few institutes in the world that offer an evidence-based specialised rehabilitation programme based on cognitive behavioural therapy (CBT) for management of misophonia, tinnitus and hyperacusis for children and adults. Our premier therapy package comprises 14 one-to-one sessions via video calls.


Multidisciplinary care

Depending on the outcome of the assessment we will formulate a treatment programme that can address issues specific to tinnitus/hyperacusis/misophonia and/or broader underlying psychological/sensory processing factors. For people experiencing comorbid psychological and/or sensory processing disorders, additional psychological and OT input will be provided throughout the treatment.


Patient support sessions

Between your main CBT sessions, you will have access to our dedicated patient support officers who will help you to practice and master the CBT techniques that you learn from your CBT sessions for managing misophonia, tinnitus and hyperacusis.


Comprehensive clinical reports

We provide comprehensive assessment report and treatment progress report summarising our findings, your diagnosis, and the treatment approach.


Research and training

At Hashir International Institute, we conduct multidisciplinary research to assess, treat, and prevent misophonia, tinnitus and hyperacusis. For healthcare professionals, we provide training courses, workshops, and masterclasses. We are a member of The CPD Certification Service in the UK.

Self help

Given that Cognitive Behavioural Therapy (CBT) is considered one of the few evidence-based tinnitus treatments and given the fact that relatively few healthcare professionals are properly prepared to deliver such treatment, it is only logical that self-help approaches have been advocated. In creating a self-help guide, Dr Hashir Aazh and Professor Brian C.J. Moore combine cutting-edge knowledge of auditory science and theoretical frameworks in modern psychology with the insight they have acquired from clinical encounters about the complexities of the human experience of tinnitus and how to help people to deal with it. But that’s not all! Aazh and Moore’s unique style of writing teaches us complex concepts in an entertaining manner. The book introduces a cast of characters from Beauty and the Beast to Moby Dick, from Dante to Muhammad Ali, and from Sigmund Freud to Rumi, Buddha and Epictetus. Packed with metaphors and practical tips, the authors draw a realistic picture of what the recovery from tinnitus-related distress looks like, and then dive into the deep and explore the variety of experiences of tinnitus and their complexities.
