The Neurophone marks a culmination of innovation and engineering spanning 45 years. The GPF-1011 DSP offers a refined aesthetic design and advanced microprocessor control to create the finest experience in ultrasonic neuropathic stimulation. The Neurophone is a precision scientific instrument with an extensive digital signal processor that encodes sound and modulates it into ultrasonic signals. 


The GPF-1011DSP offers the first, all digital Neurophone. This profound digital engineering offers a quality of ultrasonic transmission that is more accurate and rich in harmonics than an analog representation, offering a more enriching and stimulating experience. Exciting new University studies are underway evaluating the Neurophone's profound role in accelerated learning and memory retention. This instrument represents my life's work and I am greatly pleased to offer the new Neurophone Model GPF-1011 DSP.
