The BATOD Audiology Refreshers publication is now live on the BATOD website. The publication is free to access and open to any professional linked to deaf education to explore https://www.batod.org.uk/resources-category/audiology-refreshers/

Six working groups made up of dedicated chairs, co-chairs and experts working in deaf education, audiology and technology across the UK have been developing the content on

  1. Anatomy and physiology of the ear
  2. Aetiology and types of deafness
  3. Auditory perception and hearing testing
  4. Acoustics and physics of sound
  5. Listening skills and functional hearing
  6. Hearing technologies

As a live resource, further material will be added over the coming months.  If you feel something is missing, would like to offer a suggestion or contribution and/or join the working group to maintain the resource please send an email to: This email address is being protected from spambots.
