Ballachanda (founder and CEO, Premier Hearing Center) and three co-authors have written a second edition of their textbook on the human ear canal to include advances in research that have occurred since the first edition was published. Topics include anatomy of the outer ear and the ear canal, examination, pathology, acoustics, deep canal hearing aids, and cerumen management. While written as a textbook, audiologists also will find the updated edition useful. Annotation c2013 Book News, Inc., Portland, OR (booknews.com)
