| Summary: | Electrophonic hearing , stimulated by the passing of an audiofrequency
current through various electrodes attached to the body, has
previously been studied. More recently, transdermal stimulation, a
means of electromagnetic excitation utilizing an amplitude-modulated
radio-frequency stimulus applied through insulated electrodes, has received
attention. Claims of sound transmission directly to the brain
via this method have prompted several research efforts. Although most of
the results tend to disprove the claims, they have not been conclusive.
Further investigation of the transdermal mechanism is warranted. The
purpose of this work is to design and construct a device especially for
research of transdermal hearing.
