Encephalophone: An Electronic Stethoscope for the Brain

Document Thumbnail

Brain waves from normal and diseased persons can be made to produce distinctive sounds. Physicians can use the instrument for examinations and research. An audio carrier of 1700-Hz frequency modulated by the 0.5-40-Hz brain waves is the basis of design. An experimental system has been assembled, and the various sound patterns have been listened to from healthy and diseased persons. Modern technology could provide a pocket model for clinical use.
