Binaural Brainwaves

应用高达1000赫兹在左侧和右侧耳分别产生声波。

The application is intended to generate the binaural waves upto 1000 Hz on both sides i.e. left and right side separately. User has to decide the frequency of sound to generated on each side. User can customize the frequency of waves as he want below 1000 Hz.

What are Binaural Beats?

Binaural beats are auditory brain-stem responses which originate in the superior olivary nucleus of each brain hemisphere. They result from two different auditory impulses or sounds, heard from opposite ears. This binaural beat is consciously heard as the human hearing range is from 20-20,000 Hz. Rather it is perceived as an auditory beat and theoretically is being used coach certain brain rhythms from what is called the frequency-following response (the tendency for the brain to resonate at the frequency of an external stimulus).

How it works?

When signals of two different frequencies (sounds) are presented, one to each ear, the brain detects phase differences between these signals. The brain processes this anomalous information differently when these phase differences are heard with stereo headphones or speakers. A perceptual integration of the two signals in perceived in the brain, producing the sensation of a third “beat”. The difference between the signals waxes and wanes (this is the “wavy” sound heard in the hypnotic sessions) as the two stereo sounds mesh in and out of phase. The binaural beat is perceived as a fluctuating rhythm at the frequency of the difference between the two auditory inputs.

Binaural Beats types :

> 40 Hz Gamma waves Higher mental activity, including perception, problem solving, fear, and consciousness

13–39 Hz Beta waves Active, busy or anxious thinking and active concentration, arousal, cognition, and or paranoia

7–13 Hz Alpha waves Relaxation (while awake), pre-sleep and pre-wake drowsiness, REM sleep, Dreams

8–12 Hz Mu waves Sensorimotor rhythm Mu_rhythm, Sensorimotor_rhythm

4–7 Hz Theta waves deep meditation/relaxation, NREM sleep

< 4 Hz Delta waves Deep dreamless sleep, loss of body awareness
