This weekly theme is Binaural Beats and background sleep noises. YOUR OPINION IS VERY IMPORTANT FOR US. What type of sounds do you want to be featured in the upcoming episodes of the Sleep Meditation Podcast? Please give your feedback here: www.asmrsleeptriggers.com/feedback  - A binaural beats happens inside the brain, and is caused by a physiological response. Upon hearing two tones of different frequencies – sent simultaneously to the left and right ears – the brain perceives a third tone based on the mathematical difference between the two frequencies. The brain then follows along at the new frequency and produces brainwaves at the same rate of Hertz (Hz). For example this episode is made by a 75 Hz sound frequency sent to the left ear, and a 77 Hz to the right ear, the brain will process those two frequencies and perceive a new frequency at 2 Hz. Also know as a Delta wave that can trigger deep sleep and deep relaxation.
