THENATURE OFBONECONDUCTION ASSHOWN IN THEELECTRICALRESPONSE OF THECOCHLEA. ERNESTGLENWEVER, PH.D., and CHARLES W. BRAY, PH.D., Princeton, N. J.

In these experiments the fundamental nature of bone conduction has been investigated by comparing the electrical response of the cochlea produced by this form of stimulation with that produced by air-conducted sounds. This comparison is made, first of all, in terms of the functional relation between the magnitude of the cochlear response and the intensity of sounds conducted to the ear by the two methods. A further comparison is made in terms of the relative effects of lesions in the middle ear.

Electric potentials from the round window of the guinea-pig were observed by means of a cathode ray oscillograph on stimulation with sounds from a loud speaker and from a bone conduction
