Handbook of Hearing Aids.
By A. F. Niemoeller. Price, $3. Pp. 156. New York : The Harvest House, 1940.These two little books seem to the reviewer who is not an expert in the subjects involved to cover them adequately and in an interesting way. In the guide for the deafened the short chapters dealing concisely with every phase of deafness, including lip reading and the psychologic problems of the hard of hearing, seem especially useful.
