Apparatus and method for measuring the sound transmission characteristics of the central nervous system volume of humans

A method for analyzing the sound transmission characteristics of the volume occupied by the central nervous system of a human, comprising the following steps:

• (a) obtaining a digital computer and a speaker and a microphone which interface with that computer,
• (b) programming the digital computer with a computer program which is capable of (i) generating a spectrum of sounds for output through the speaker which ranges between pre-selected low frequency and a pre-selected high frequency and transmitting that sound to the speaker, (ii) receiving data from the microphone during the sound output of step (b) (i) and analyzing that data to determine the frequency of the sound detected by the microphone and its intensity in decibels such that sounds ranging between the low frequency and the high frequency are detected and measured for both frequency and intensity and (iii) generating an output showing the sound received by the microphone in terms of sound intensity in decibels as a function of sound frequency,
• (c) running the program of the digital computer of step (b) while placing the speaker and the microphone in a spaced apart relationship on the surface of the back of a human test subject proximate to the spinal column,
• (d) analyzing the output of the computer program of step (b) to determine if the sound propagation characteristics of the volume occupied by the central nervous system of the test subject are normal in a way that substantially rules out an abnormal condition or disease state or abnormal in a way that may indicate an abnormal condition or disease state.
