The Pamphlet Collection of Sir Robert Stout: Volume 38



A Word Concerning the Very Deaf—False Teeth—And those Using Ear Trumpets.

Persons who have been very deaf for many years, and who are accustomed, wholly or in part, to interpret sound by the movement of the lips of the party speaking, may not readily distinguish the words of the speaker when first using the audiphone, though the sound of these words will be distinctly heard. In all such cases a little practice will be required to enable a deaf party to rely wholly upon sound. Such persons should request a friend to read aloud while they (the listener) should carefully observe the words (as spoken) in a duplicate book or paper. "When this is properly done the deaf person will be sur-prised with what distinctness every word is heard by the use of the audiphone. In this way they educate themselves page 6 to articulate sounds, and soon learn to hear well without observing the movements of the lips.

Persons having false teeth, if they fit firmly, can, notwithstanding, use the Audiphone successfully.

It should be further noted, that persons using such instruments as ear trumpets, etc., which in all cases increase the deafness by concentrating an unnatural force and volume of sound upon the impaired organ, should at once lay aside all such devices on receiving the Audiphone. Such persons, thus accustomed to the unnatural sound, through the ear trumpet, will require some practice to again familiarize themselves with the natural sound of the human voice which, the Audiphone always conveys.
