Therapeutic tuning fork – 40Hz Gamma wave – For sound therapy, sonology


Gamma waves are known to promote creativity and relaxation.


Gamma brain waves are located approximately between 30 and 80 Hz. 40 Hz therefore represents an average.


Gamma waves demonstrate great brain activity, such as during creative processes (creative excitement) or when solving or resolving problems (intelligence, synthesis). They manifest the completion of a process during which attention is sustained and connections are established. Gamma waves are characterized by intense neuronal and mental activity. Gamma waves radiate and are present in all parts of the brain.

The 40 Hz Gamma tuning fork is most often used with a second Gamma tuning fork and the other tuning forks from the Brain Tuner Set (brain waves)


This tuning fork is used alone or in pairs when listening at ear level combined with a second Gamma 40 Hz tuning fork.


The 40 Hz Gamma tuning fork can also be used in combination with the 32 Hz tuning fork, to create an Alpha wave at 8 Hz.


The combination of the two frequencies 40 Hz and 32 Hz reveals a 3rd vibration, called the 3rd sound or beat. The frequency obtained by the interference of the two tuning forks is 8 Hz. This inaudible frequency manifests itself on the sub-acoustic level, represents the difference between the two, i.e. a frequency in correspondence with the Alpha waves of the brain, known to favor relaxation.




Brain waves designate a set of electromagnetic oscillations in a given frequency band, most often infrasonic, except for Gamma waves and the most acute Beta waves. They result from the electrical activity of the brain which brings a large number of neurons into coherence. Brain waves are observed using the electroencephalograph (EEG).


Brain waves are characterized by a very low amplitude, of the order of microvolts, and are very changeable: they vary constantly and rarely obey a regular oscillation.


The principle of the Gamma tuning fork is to imitate these electrical frequencies by transposing them into a stable acoustic frequency, which acts in resonance and which regulates their natural production.
