Acoustic beats: the basis of the Infrasonics therapy

The new therapy for treatment of sleep disorders.
Scientifically tested and effective.

At any time of day and night, the brain’s activity can be characterized by the electrical activity in the cortex, which takes the form of cyclical activity in a range of frequencies up to ca. 30 Hz (the so called „brainwaves“, which can be measured via an electro-encephalogram). In a healthy subject, the dominant frequencies will be characteristic of the type of activity in which the subject is engaged at any point in time. For example, during activities requiring a high level of concentration and/or vigilance, the higher frequency range (15 to 30 Hz) typically dominates, while in healthy sleep, the strongest measurable activity is within the lower frequency range (2 to 6 Hz). However, subjects with sleep disorders typically display a non-conform pattern of brainwave activity: the brain is not able to adjust itself to lower frequencies, and the subject is disturbed by often erratic activity in higher frequencies.

Here is the basis of Infrasonics’ unique active principle:

Infrasonics’ inPulser produces specially calibrated acoustic signals which, among other things, include specific frequency and amplitude modulations designed to supportthe production of brain waves in the appropriate frequencies, while inhibiting the production of waves in the (higher) inappropriate frequencies. To that end, several physical and neurological phenomena are being leveraged, in particular binaural beats, monaural beats and isochronous tones. The Somnia programs, encoded on SD-flash-cards, reproduce within a 90-minute cycle the frequency pattern typical of a healthy and regenerating sleep cycle.

The effectiveness of this therapy has been confirmed by four independent clinical trials, both in slep laboratories with EEG monitoring, and in “live” setting with over 100 patients using the system in their home. Infrasonics’ inPulser is the only therapeutic system based on acoustic stimulation whose effectiveness in the treatment of sleep disorders has been confirmed in such a solid and independent manner. It is using leading-edge audio-technology in order to reproduce the acoustic signals at the appropriate level of resolution, while totally avoiding the erratic frequency patterns which are produced by mainstream methods of music encoding and compression (in particular MP3 format).
