3 Hours Grey Noise + 2 Hz Delta Binaural Beats | Deep Sleep & Relaxation | Black Screen

3 hours of grey noise and 2 Hz delta binaural beats for deep sleep, relaxation and overnight rest, all on a black screen with no music. WHAT IS GREY NOISE? Grey noise is a special type of noise that is similar to white noise, but instead of treating all frequencies with equal energy, grey noise is designed so that all frequencies have the same loudness. The difference is that the human ear is sensitive to different frequencies, which means that two frequencies do not have the same loudness when played with the same energy. We've designed this audio to have a similar characteristic. This gives grey noise a characteristic texture of both a low rumble and a high hiss. WHAT ARE BINAURAL BEATS? Binaural beats are a type of sound that requires two tones, one in the left ear and one in the right. These tones are of slightly different frequencies, the most commonly that difference is between 2-40 Hz, and in this video it's specifically 2 Hz. The two tones interfere in the brain, which creates a pulsing ('beating') effect. The idea is that the brain synchronises its activity to the difference in frequencies. 2 Hz specifically is associated with deep sleep and rest. HOW CAN THIS HELP ME? You can use this audio for whatever you like, but we recommend that you use it when you want to fall into deep sleep or relaxation. HOW DO I USE THIS? Stereo headphones are most effective for this audio and we highly recommend them, as the beating effect has to happen in your head rather than from the speakers in your headphones. We've made the audio with a comfortable listening volume of 15-25% system volume in mind, but as always this varies from device-to-device, including your specific model of headphones, the device you're using to watch this video, and the environment you're in. We recommend that you listen to this audio in a quiet environment, as that is generally conducive to relaxation. We've made the majority of this video black for those who aren't on YouTube Premium to help them save battery. If you're on mobile and you have YouTube Premium, you can set the volume to your comfort and then just turn off your screen and continue to listen to the audio. If you're on mobile and you do NOT have YouTube Premium, we recommend setting the screen brightness as low as possible to save battery while listening to the audio.
