PURE 40 Hz Isochronic Tones | BLACK SCREEN | INTENSE Focus, Work, Study SCREEN FADES TO BLACK AT 01:00 WHAT ARE ISOCHRONIC TONES? Isochronic tones refer to a type of audio which includes a single tone that pulses on and off at evenly spaced intervals. It is quite often used for a process known as brain entrainment - the idea that audio can influence a brain to synchronise its brainwave activity to the frequency of the audio. We make no claims to the effectiveness for this audio, as we make each audio for entertainment and relaxation purposes only. In this video we use a base frequency of 200 Hz which pulses on and off 40 times per second (40 Hz). HOW CAN THIS HELP ME? You can use it for anything, but we recommend that you use this audio for deep focus sessions as this audio was designed with focus in mind.

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 or speakers, 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 focus. 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.
