Can you tell the difference between mono sound and stereo? If you were scanning through radio stations, would you be able to tell if you were listening to music in mono or stereo sound? More specific, and harder to identify, is the difference between high bitrate versus MP compressed files in the sound range reproduction of music. Can you consciously tell the difference in the auditory experience? Well whether you are acutely aware of these differences, as some people are, or not, your brain knows.
Binaural beats and auditory wave stimulation
Binaural recording is a method of recording sound that uses two microphones, arranged with the intent to create a 3-D stereo sound sensation for the listener of actually being in the room with the performers or instruments. This effect is often created using a technique known as “dummy head recording”, wherein a mannequin head is outfitted with a microphone in each ear. Binaural recording is intended for replay using headphones and will not translate properly over stereo speakers. This idea of a three dimensional or “internal” form of sound has also translated into the useful advancement of technology in many things such as stethoscopes creating “in-head” acoustics and IMAX movies being able to create a three-dimensional acoustic experience.
Binaural sound, therefore, creates a more complete soundscape than it has been previously achieved in artificial conditions. The methodology, by nature, feeds directly into the brain via audio nerve stimulation.
Selecting the right frequencies
“Do you know that our soul is composed of harmony?” – Leonardo da Vinci
According to Wikipedia’s definition, Isochronic tones are regular beats of a single tone that are used alongside monaural beats and binaural beats in the process called brainwave entrainment. At its simplest level, an isochronic tone is a tone that is being turned on and off rapidly. They create sharp, distinctive pulses of sound. (https://en.wikipedia.org/wiki/Isochronic_tones)
Primarily, these work on your auditory circuits. The soundwaves stimulating your auditory nerves follow a complex path from stimulation to producing an effect. The effect is profound if you analyze all the processes and subsequent effects such sound has on the physical and neurobiological state of the brain.
Synctuition’s programs combine a number of authentic and natural sound sources and reproduce them using the latest technologies in order to produce sound and binaural and isochronic programs that are closely matched to your personal achievable results.
Synctuition works through stereo headphones* by playing one frequency in your left ear, and a slightly modified frequency in your right ear. This causes your brain to naturally create a third frequency, which exists only in your mind. This third frequency is called a binaural beat and it stimulates the left and the right side of your brain to work together in synchronization in order to reconcile the different frequencies you hear through the headphones.
A binaural beat is an auditory illusion perceived when two different pure-tone sine waves, both with frequencies lower than 1500 Hz, with less than a 40 Hz difference between them, are presented to a listener dichotically (one through each ear).
There is conclusive scientific evidence that certain frequencies, like those achieved in repetitive drumming, can alter cortisol levels in salivary tests on subjects undergoing this experience. (Cortisol is a stress indicator hormone)
Exposure to repetitive drumming combined with instructions for shamanic journeying has been associated with physiological and therapeutic effects, such as an increase in salivary immunoglobulin A. In order to assess whether the combination of repetitive drumming and shamanic instructions is specifically associated with these effects, we compared the effect of listening to either repetitive drumming or instrumental meditation music for 15 minutes on salivary cortisol concentration and on self-reported physiological and psychological states. For each musical style, two groups of participants were exposed to two conditions: instructions for shamanic journeying or relaxation instructions. A total of 39 participants (24 females) inexperienced in shamanic journeying completed the experiment. Salivary cortisol concentrations were measured before and after exposure to music. In addition, participants filled out a mood questionnaire before and after the experiment and completed a post-experiment questionnaire on their experiences. A significant decrease in the concentration in salivary cortisol was observed across all musical styles and instructions, indicating that exposure to 15 minutes of either repetitive drumming or instrumental meditation music, while lying down, was sufficient to induce a decrease in cortisol levels. However, no differences were observed across conditions. Significant differences in reported emotional states and subjective experiences were observed between the groups. Notably, participants exposed to repetitive drumming combined with shamanic instructions reported experiencing heaviness, decreased heart rate, and dreamlike experiences significantly more often than participants exposed to repetitive drumming combined with relaxation instructions. Our findings suggest that the subjective effects specifically attributed to repetitive drumming and shamanic journeying may not be reflected in differential endocrine responses.
Isochronic tones are generally sharp, pulses of sound. repetitive beats of a single tone that is being turned on and off rapidly recorded alongside monaural beats and binaural beats in brainwave entrainment.
A program consisting of a combination of isochronic, binaural and personalized frequencies can, therefore, achieve results that would take far longer to entrain through just one stimulus. The multiple channels stimulated in your brain when using these programs, especially if you do so consistently and repetitively, results in a process called entrainment. Entrainment is basically your brain responding to the mental muscles you have been exercising.
