Tuning fork set Brain waves

Model : STF20

Set of 5 tuning forks based upon four different types of brain waves, namely: Delta, Theta, Alpha, and Beta. Plus one fundamental brain tuning fork.

These brain waves are connected to different activities of the human brain:
- Beta waves: Thinking, concentration, arousal, cognition.
- Alpha waves: Relaxation (while awake), pre-sleep and pre-waking drowsiness.
- Theta waves: REM sleep, dreaming, deep meditation.
- Delta waves: Deep sleep (dreamless), loss of body awareness.

When the fundamental brain tuning fork is sounded with any of the 4 brain tuning forks (one at each ear), the difference between the two tuning forks creates a binaural beat which can be heard/percieved as a pulsation. The difference between the two frequencies must be small for the effect to occur; otherwise, the two tones will be heard separately and no beat will be perceived.

Binaural beats reportedly influence the brain in subtle ways through the entrainment of the brainwaves, and can be used to induce relaxation and other health benefits such as pain relief.
