Dr. G. Frank Lawlis developed the Bio-Acoustical Utilization Device (BAUD)- Binaural Pulse Modulator (BPM) and it represents one application of binaural auditory stimulation. The binaural auditory phenomenon was first reported by H. W. Dove in 1839 and outlined in detail by Oster (1973). Oster noted that the binaural frequency was detected only when two different tones were presented to an individual and the main frequency was below 1000 Hz. This indicates that frequency has to be sufficiently low enough to be temporally encoded by an individual’s brain.
The BAUD-BPM was developed following the use of auditory stimulation via drum beats used as part of treatment for a clinical population by Dr. Lawlis. He had done this following his consulting with someone familiar with Shamanic healing and the use of various types of music and rhythmic drumming to alter consciousness for centuries. Evidence exists to substantiate the impact of auditory stimulation on the waveforms produced by neural firing in the brain. The BAUD-BPM is a device that can be used to assist self-regulation through auditory tones that have been demonstrated to influence brain functioning at the unconscious level as well as perceived emotional changes. Brain waveforms are directly related to
moods and concentration levels experienced by individuals, it is logical to suggest that if the sounds produced by the BAUD-BPM result in beneficial results that would be clinically beneficial as an adjunctive tool in a variety of settings.
Furthermore, research has shown that 4 weeks of BAUD-BPM use (twenty minutes twice a week) was associated with changes in the brain as seen on QEEG and fMRI. Additionally, research has shown that over the same 4 weeks, BAUD-BPM use was associated with reduced severity of emotional distress including anxiety and PTSD on self-report surveys.
