Open access guide to audiology and hearing aids for otolaryngologists

This is a free textbook and is intended particularly for ENT surgeons practising in the Developing World who are unable to access audiology services or audiology textbooks. The textbook is still in evolution, and chapters will be added as they are completed over the coming months. Clicking on completed chapters (in blue) provides access the PDF documents. There are no copyright restrictions, and colleagues are welcome to use, copy and quote text as they wish.
