Audiology Refreshers

This web publication of the BATOD Audiology Refreshers is produced with the support of Oticon

Items published by BATOD in the Association Magazine over several years.


Teachers of the Deaf have many issues to deal with in their jobs. The mandatory qualification training for Teachers of the Deaf includes basic audiology. Detail may be forgotten when the knowledge has not been used for some time in daily practice.

This series of articles has been written to give Teachers of the Deaf, students and other professionals working with deaf children quick access to refresh their memory of basic audiological knowledge and practices. It is not intended that these refreshers replace basic training and further information may be gleaned from books on the specific audiological subject.

The Refreshers were originally published over several years in issues of the BATOD Magazine. In this copy some of the details have been updated but otherwise the sheets remain as they were originally although the layout may have changed.

Some relevant articles have appeared in the Magazines which extend and enhance the information in the Refresher series and they have also been included where relevant. It is our intention that updates and new ‘Refreshers’ will be added to this collection as appropriate.

The Audiology Refresher series was originally conceived by Margaret Glasgow who wrote many of the pages.  In addition, there have been many colleagues who have contributed pages and articles.  We are grateful for their contributions and those who have assisted in the production of this publication especially Rosi Hearnshaw for her technical expertise in redrawing and reorganising the pages, Corinda Carnelley and Liz Reed-Beadle for proofing.  Most importantly BATOD thanks Oticon for their sponsorship of these Audiology Refreshers which are freely available on the BATOD website.

Ann Underwood, BATOD President 2008-2010

Note from National Executive Officer:

Although these refreshers were written some time ago they are still relevant. However, if you feel any amendments or further updates are needed, please let us know by writing to
