Auditory Processing Disorder Interest Group

The APD SIG promotes a high standard of research and evidence-based care and encourages international and interdisciplinary collaboration.

Who are we?

The APD SIG, was established in 2003 and is the first BSA SIG. Our steering committee represents a broad range of professional disciplines, and includes leading researchers and clinicians in the field. We foster strong links with the community and individuals with APD as well as their families. We invite both professionals and members of the public to serve as advisors to our SIG.

What is our aim?

The aim our APD SIG is to promote a high standard of research and evidence-based care and encourage international and interdisciplinary collaboration.

Our APD SIG has been at the forefront of international developments in recent years. The new Position Statement and Practice Guidance APD 2018 was published in February 2018. Please note this document updates rather than replaces the existing 2011 documents. These documents should be read together. The BSA APD Position Statement and Practice Guidance Document, published in 2011, served as a catalyst for moving the field of APD forward and fostering international collaboration.

The above 2011 documents culminated in the publication the first BSA ‘white paper’ with a set of international commentaries from experts around the world: David R. Moore, Stuart Rosen, Doris-Eva Bamiou, Nicole G. Campbell & Tony Sirimanna (2013) Evolving concepts of developmental auditory processing disorder (APD): A British Society of Audiology APD Special Interest Group ‘white paper’, International Journal of Audiology, 52:1, 3-13, DOI: 10.3109/14992027.2012.723143

The APD MeshGuide, an online resource published in 2019 (and regularly updated), offers a snapshot of APD, access to international position statements/practice guidance.  The APD MeshGuide is structured to allow the reader to easily access the specific area/s they are interested in.

What is an Auditory Processing Disorder?

APD is characterised by poor perception of sounds, has its origins in impaired neural function, and impacts on everyday life primarily through a reduced ability to listen, and so respond appropriately to sounds. There are 3 categories of APD:

  1. Developmental APD: Cases presenting in childhood with listening difficulties, but with normal audiometric hearing and no other known aetiology or potential risk factors other than a family history of developmental communication and related disorders. These individuals may retain APD into adulthood
  2. Acquired APD: Cases associated with ageing or a known medical or environmental event (e.g. brain lesion)
  3. Secondary APD: Cases where APD occurs in the presence, or as a result of either transient or permanent peripheral hearing impairment
