Dr. Hashir Aazh BSc, MSc, PhD (Audiologist, Specialist in Tinnitus & Hyperacusis Rehabilitation)
Dr. Hashir Aazh, is an audiologist with special interest in rehabilitative audiology. He is the head of the Tinnitus and Hyperacusis Therapy Specialist Clinic as well as clinical research lead at Audiology Department, Royal Surrey County Hospital, Guildford, UK. His clinical work focuses on providing specialist therapies for adults and children experiencing tinnitus, hyperacusis and misophonia.
Over the past decade, Hashir has developed an applied conceptual framework for audiologists and mental health professionals in order to assess and manage the distress linked to tinnitus, hyperacusis and misophonia in children and adults. This framework was based on the concepts emerged from his tinnitus team’s research and innovative clinical practice in combining methods of cognitive therapy with audiological science in the context of tinnitus and hyperacusis rehabilitation. The key highlights of his work comprise:
- Using in-depth interviews in combination with audiological and psychometric data in order to pinpoint and assess tinnitus and/or hyperacusis related distress.
- Distinguishing between tinnitus- and/or hyperacusis-related distress and the distress caused by other psychological disturbances in those who happen to also suffer from tinnitus and/or hyperacusis.
- Evidence-based criteria for screening and referring patients to mental health professionals.
- Suicidal and self-harm ideations in patients with tinnitus and hyperacusis
- Methodology for cognitive behavioural therapy focused on tinnitus- and/or hyperacusis-related distress
- Diagnosis of hyperacusis
- Mathematical model describing the relationship between hearing loss and tinnitus
- Mathematical model describing the relationship between insomnia and tinnitus
- Mathematical model describing the relationship between depression and tinnitus
- Adverse childhood experiences and tinnitus disability
- Geriatric tinnitus and hyperacusis
- Paediatric tinnitus and hyperacusis
Hashir has written over 40 scientific papers in the field of Audiology. In 2009 he was awarded the Joss Millar Shield from the British Society of Audiology.
Hashir is an Associate Editor for the International Journal of Audiology, guest Editor of Noise & Health, and reviewer for The Laryngoscope, Psychosomatic Journal, BMJ, and The New England Journal of Medicine.
Hashir is the course director for the tinnitus and hyperacusis therapy masterclass. He recently organised a highly regarded specialist training course for audiologists, otolaryngologists, psychiatrists and psychologists in Melbourne (Australia) on tinnitus and hyperacusis rehabilitation.
Hashir is the organiser of the International Conference on Hyperacusis: The relationship of Hyperacusis with Noise Sensitivity, Tinnitus, Hearing Loss and Misophonia (http://hyperacusisresearch.co.uk/). Hyperacusis conference is suitable for professionals as well as patients.
Hashir supervises MSc students at University of Surrey and is the research and development lead at Audiology Department, Royal Surrey County Hospital. His current studies focus on:
- Specialist therapy for tinnitus, hyperacusis, and misophonia rehabilitation
- Factors related to tinnitus and hyperacusis handicap in old age
- Factors related to insomnia, depression and anxiety in patients who experience tinnitus, hyperacusis, and misophonia
- Tinnitus, hyperacusis and misophonia in children and teenagers
- Causes of hyperacusis and misophonia
- Therapy for auditory imagery
1) The definition of hyperacusis which was proposed by Hashir and his colleagues and published in the International Journal of Audiology (2016) has been used by the NHS choices and the British Academy of Audiology. This definition was ground-breaking as it made it clear that hyperacusis is only present when intolerance to sound causes significant distress and impairment in the individual’s life. Being sensitive to certain sounds without developing significant distress doesn’t classify as hyperacusis hence there is no need for any treatment for such cases.
2) Hashir’s research in the field of audiology has influenced the British guidelines for hearing assessment, aural rehabilitation, and Forensic Neuropsychology.
3) Over 500 professionals (audiologists, hearing aid dispensers, physicists, psychologists, ENT, psychiatrists, and hearing therapists) have been trained by Hashir in his Tinnitus and Hyperacusis Masterclass worldwide.
4) Hashir is the Audiology champion for research in Surrey, Sussex and Kent Clinical Research Network, National Institute of Health Research (NIHR).
