Claim One:
1. A method of evaluating auditory steady state responses comprising: administering, by an auditory signal generator, an auditory stimulus to a subject at a predetermined frequency to generate an electrical activity in the subject; synchronizing the electrical activity in the subject with the auditory stimulus to define an auditory evoked potential; measuring, by a sensor, amplitudes of the auditory evoked potential; identifying, by a processor coupled to the sensor and configured to receive the measured amplitudes of the auditory evoked potential therefrom, a plurality of spectral components of the auditory evoked potential, the plurality of spectral components comprising a fundamental frequency and one or more harmonic frequencies; and calculating, by the processor, a harmonic sum of the plurality of spectral components to determine an overall amplitude of the auditory evoked potential, the harmonic sum comprising a square root of a sum of the amplitudes squared of the auditory evoked potential at the fundamental frequency and the one or more harmonic frequencies.
