The National Institute on Deafness and Other Communication Disorders reports that more than 28 million Americans are deaf or hard of hearing; over 30 million more are exposed to dangerous levels of noise. Levels of hearing impairment vary from mild but important loss of sensitivity to a total loss of hearing. Living with Hearing Loss provides important and up-to-date information to help readers understand hearing impairment and how it can be successfully treated. More than 800 entries cover parts of the ear
I didn't read the whole book. The last half is a list of things related to hearing loss, which I looked at but didn't read all of it. The first half of the book gives some information on signs of hearing loss, causes, and information on hearing aides and cochlear implants. It gives a decent overview of the topics. It doesn't give much in depth information though.
