Two processes are utilized in the practice of human bioacostics – vocal profiling, and sound presentation. Vocal profiling is a method used to gather data from the human voice as a portrayal of the significant frequency features and architecture and investigated for their relationship to anatomical, physiological, or emotional imbalance.[10]

A bioacoustic therapy session begins with the client speaking into a microphone for 30 seconds. This voice sample is then used to establish harmonic patterns that govern the person’s Signature Sound. The data is entered into a computer program which converts the sample with fast Fourier transform (FFT) algorithm to a chart representation of the frequencies, amplitudes, and architecture of the voice. Frequencies represented on the chart as points that are much higher, much lower, or dissident are used to construct frequency formulas that will be tested during tone trials, a process where the person listens to these sounds while being monitored with biometric equipment for changes in heart rate and oxygen saturation. Charts displaying a unified pattern with few frequency amplitudes in the high and low range indicate greater coherence.[10]
