Isochronic Tones – Deep Sleep Aid

Whether you are a mother wanting to use baby sleep music, a teenager suffering from ADHD, an adult suffering from work stress or a senior having trouble getting a good night’s sleep – our channel will provide relaxation music to battle these issues.

Or do you know what it feels like to get your full 8 or 9 hours of sleep but still wake up feeling groggy and tired? I think we all know that feeling.

It can be incredibly frustrating to know that you slept through the night and yet you don’t feel like you actually got enough rest. What gives?

Well, not all sleep is equal. It’s likely that you didn’t get enough deep sleep, which is where all the healing and rejuvenating magic happens.

What is Deep Sleep?

Sleep isn’t just a constant state of being. We go through various stages of consciousness during the night. Deep sleep is the stage the body goes into after we fall asleep properly.

This sleep stage is highly important. Not that the others aren’t, but this is when growth, repair to tissues and bones, and cell regeneration takes place and our immune systems are strengthened.

Sleep Stages

When we go to bed, our body will move through 5 different stages of sleep. These consist of REM (Rapid Eye Movement) and NREM (Non-Rapid Eye Movement) stages, and they both serve different purposes.

You’ll go through this cycle between four and six times in a single evening! We spend up to 90 minutes in each cycle.

Every stage of sleeps has a unique purpose and restorative function, which includes hormone regulation, memory consolidation, cell regeneration and muscle recovery.

Without a full night where deep sleep has been achieved, you’ll find that recalling information can be difficult, your immune system may weaken, and it can also lead to weight gain!

How Does Music Help with Deep Sleep?

Sleep music uses something called binaural beats. We’ll explain them further down, but these sounds trigger changes in the body that slow the heart rate and breathing, lower blood pressure and relax the body. The parasympathetic nervous system is directly stimulated, which helps you fall asleep quicker.

The frequency of deep sleep music is similar to the frequency of real sleep (yes, sleep has a frequency!), which starts from below 1 Hz. It ends at around 7 Hz, which is when you start to wake.

As you become more alert, the frequencies increase. The frequency of the binaural beats in the delta stages (Stages 3 and 4, between 1 Hz to 4 Hz) is associated with relaxation and deep sleep.

Types of Deep Sleep Music

There are two types of deep sleep music: binaural beats and isochronic tones for deep sleep. There are some subtle differences between the two, and it really comes down to personal preference as to which works best.

If you haven’t tried listening to sleep music before, you may want to try both and then choose the one that works best for you!

  • Isochronic Tones

Isochronic tones are composed of a single tone that pulses very quickly. It’s like listening to a rhythmic beat, and they’re often layered with the sounds of nature or gentle music. Your brain’s frequency syncs with the music, which will start the sleep process. It’s quite worth trying Isochronic tones for deep sleep.

  • Binaural Beats

Binaural beats use two tones – one in each ear, each at a slightly different frequency. Your brain processes the difference in the frequency, and will then fall into sync with the difference of the beat.

For example, if you have a frequency of 142 Hz playing in your left ear and a frequency of 131 Hz in your right ear, your brain will sync with the difference of 11 Hz. You won’t hear two tones. You’ll only hear the one tone at 11 Hz.

In order to be a true binaural beat, the two tones need to have frequencies that are less than 1000 Hz combined, and the difference can’t be more than 30 Hz. It’s pretty technical!

The best way to listen to binaural beats is through headphones, as the tones have to be listened to separately by each ear.


Don’t underestimate the power of deep sleep music to help you get a more restful night’s sleep! Just like sometimes we need a little motivation to get work done or get out of bed, sometimes our brains need a little help getting into the right zone for optimal rest.

Why not give some binaural beats or isochronic tones for deep sleep a try?
