Each slider controls a particular frequency. Adjust sliders to induce a particular mental state. Mixing adjacent sliders works best.


Our brainwave generator specifically outputs frequencies that replicate the cycles of brain waves. By syncing up your brain with these frequencies, your state of consciousness will be altered.

Because of the strong and repetitive pulsating rhythms, people who are prone to seizures or epilepsy should not use our brainwave generator. Children and pregnant women should also use caution when considering using brainwave entrainment.

The Missing Frequency

myNoise Binaural Beats generator, is a popular brainwave entrainment player on the internet, with hundreds of listeners every day. It covers most frequencies, from low delta (1 Hz) up to low gamma (32 Hz).

Recent scientific papers suggest that higher frequencies in the gamma range - and 40 Hz in particular - could be more effective than any other frequency for improving memory and attention. It didn't take long for visitors to begin requesting that frequency from me. Here is what they were looking for, along with some explanation as to why that frequency wasn't included the original brainwave entrainment generator.

Brainwaves are electrical waves characterized by frequencies that would be below our hearing range if they were sound. Researchers have devised various techniques to embed this inaudible signal into an audible sound and then use it as a stimulus. Popular techniques are binaural beats, isochronic and bilateral modulations.

40 Hz is unusually high for a brainwave and is already a frequency that humans can hear! This is why I didn't consider including it in the binaural beat generator: it didn't need binaural beats in order to be audible. Unfortunately, this special frequency was not to be found elsewhere on the website. Until now.

The first slider of this generator plays 40 Hz, raw, in its purest sinusoidal form. Though audible, it is still a low frequency, one that will NOT cut though small speakers.

Don't try to hear it on your mobile phone, laptop, or tablet speakers, it won't work. Use headphones instead.

The next sliders use that same frequency but as a carrier embedding other brainwave frequencies. This hasn't been offered elsewhere yet! They play two brainwaves simultaneously: 40 Hz gamma as a carrier and slower brainwaves as a binaural beat embedded in thise carrier. Headphones are again strongly recommended.

Finally, the last slider uses a much higher carrier frequency, offering 40 Hz as a pure binaural beat, instead of a raw frequency.

Experimenting with audio signals should be harmless as long as you keep the levels safe. Beware though of the preset called "Adrenaline Rush," which embeds a very strong modulation. If you don't feel comfortable while listening to it, or to other preset, just leave this page and you will be fine.

  I'm so happy that I have a sub bass speaker hooked up to my PC along with my studio monitors. It's consumer grade stuff for the home musician but I can hear and feel this pulse! I can sit here and work from home with this on, I feel like I am crashing through all the mundane stuff and being very productive!

  This is great! I am working and need a subtle boost! Other brainwave entrainments tend to give me a headache, but not this one. More of these please!

  This preset is not included. I always use Beta since I have ADHD+. But there is not a Gamma + Beta wave. Here I created the Gamma + Beta Highway. Thank You.

  Wow, this is so good with the right output devices. Thank you. Also, autistic, fwiw. Very satisfying, just makes me feel like the universe is inside of my brain and that everything is just okay or something.

  I am studying for a professional designation. So I am studying on the weekend because I work fulltime during the week. This setting of Gamma + Binaural Alpha helps me focus, alert but not too activated so I can learn. Remember, I am tired on the weekend from working all week. Thank you Dr P for creating this gen! I hope this case study helps.

  Most settings I try just make it harder to breathe for some reason, regardless of which setting it is. I'll be sure to come back and check the testimonials for others' results once the page gets a better chance to reach people :)

  Thank you so much for this. You obviously care about your visitors, and we care right back!

  She cannae take any more, captain! She's gonna blow!

  This is a slightly modified 'Beta Highway' setting. It helps me focus. I'm honestly surprised how well these gamma waves work, I expected them to put me to sleep immediately instead of sobering me up. Note: may not be very suitable if you are looking for something to mask the background noises.

  Hi Dr Pigeon, this is a question for you. I am playing around with the sliders, but do not know if I'm creating delta vs beta vs alpha. I see the presets. Would you include in the explanation what +3Hz vs +4Hz vs +7Hz, etc Hz does? I love your work. I want to make this gen work fantastically! Thanks. [Editor's note: have you read the introductory text? It's explained there.]

  Ok wow. Genuinely messes with me but in a good way. :&
