Resumen
Hearing from sound being conducted through bone of the jaws and skull, called bone conduction, has a long history. Berger described hearing through bone conduction appliancesdating backto Claudius Galen' s writings (131-200AD) with numerous variations in Europe, Scandinavia, and England, ali the way up to the 19th century.' Staab's excellent review of "The Origins of Bond Conduction Hearing," throughout the centuries, can be accessed online: . http:// hearinghealthmatters.org/waynesworld/2012/theorigins-of-bone-conduction-hearing/ There was much activity with tooth hearing devices in the 1880s and 1890s and into the early 20th century. These were devices were called Audiphone, Dentaphone, Osteophone, Electrophone, and a number of "acoustic fans" such as the Audinet.
Toe person using these devices would place he upper edge of the fan against the maxillary incisors (Figure 1A). Sound waves would propagate through the fan, which was under tension, and the vibrations would pass on through the teeth.
Sorne of the inventors who patented their devices in this era were: Charles Hermon Thomas - Osteophone (1879), Walther W. Bostwick - Dentaphone (1879) Francis D. Clarke and Macomb G. Foster -Electrophone (1880) Richard Silas Rhodes - Rhodes Audiphone (a.ka. Rhodes Acoustic Fan) (1879) Orel Dighton Orvis - Fan similar to the Rhodes device (1880) Samuel Sexton - Otacoustic fan (in Japan) -sheets oflacquered bamboo (1881) Thomas William Graydon - Audiphone and Dentaphone {1880)
