Professional impact

  • 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.
  • Hashir’s research in the field of audiology has influenced the British guidelines for hearing assessment, aural rehabilitation, and Forensic Neuropsychology.
  • Over 200 professionals (audiologists, hearing aid dispensers, physicists, psychologists, ENT, psychiatrists, and hearing therapists) have been trained by Hashir in his Tinnitus and Hyperacusis Masterclass worldwide.
  • Hashir is the Audiology champion for research in Surrey, Sussex and Kent Clinical Research Network, National Institute of Health Research (NIHR).
