Phonocephalography is the amplification and recording of sounds from the surface and cavities of the head aiming for the introduction of a non-invasive pre-angiographic technique. Nasopharyngeal Phonocephalography was found successful for recording of normal tracing. The effect of the extra-cephalic sounds and factors on the tracing were discussed. Phonomyelography is the application of the idea on the vertebral column. The tracing recorded was demonstrated. Modern technology has undergone considerable progress for the introduction of non-invasive techniques in medical diagnosis. Since Laennec introduced his stethoscope auscultation, amplification and recording of sounds in cardiology had reached a respectable diagnostic procedure. This article represents a trial for the introduction of a simple non-invasive pre-angiographic diagnostic technique by amplification and recording of sounds from the surface and cavities of the body.
