What is Human BioAcoustic Vocal Profiling? Using a uni-directional condenser microphone that is linked to a computer equipped with a calibrated sound card, a short (less than a minute) sample of the voice is captured. A Fast Fourier Transform (FFT) converts the recorded vocal sounds into numeric data using the properties of frequency (Hertz/cycles per second) and amplitude (decibel). This information is used to create a digital graph that represents the vocal frequencies and the corresponding data using a range of 0-1000 cycles per second. FFT’s are computationally efficient algorithms commonly used to convert analog vocal data to digital numeric data for rapid spectral analysis. Such transformations from time to frequency domain use mathematical functions to depict the relative magnitudes and phase relationships of frequencies in a time varying signal.

What is Human BioAcoustic Sound Presentation? Sound presentation, BioAcoustically speaking, is the delivery of analog sequenced frequency sets, via headphones or a speaker, that are individually constructed for a client using information gleaned from a Vocal ProfileTM by a trained BioAcousticResearch Associate/Assistant. After a vocal sample is captured, computer analysis is used to determine the most appropriate frequencies that will be evaluated during tone trials. These frequencies are established using information supplied by the referring physician, reported issues from the client, data from vocal samples, comparisons against other client vocal prints who have similar  issues and a client’s responses during sound presentation.
