What makes SonicTonic unique is its expertly crafted tonics. All you need to do is sit back, relax, plug in your headphones and let the relaxing sounds take you on a journey. You don’t need to learn anything, there’s no meditation involved, instead each and every tonic administers a good strong dose of Receptive Sound Therapy to help you manage stress, sleep better and focus more.

So, what is Receptive Sound Therapy and how can it help you to manage your stress, sleep better and put you into a better state of mind. We’re here to tell you all about it.

What is Receptive Sound Therapy?

Receptive Sound Therapy is the clinical use of recorded sound, music, or spoken word, or combination thereof which, when listened to, has beneficial physiological, psychological or social effects. There are also studies that show that Receptive Sound Therapy can improve concentration, boost motivation and increase energy.

SonicTonic uses 5 special ingredients in the various tonics: binaural beats, Isochronic tones, Solfeggio frequencies, ASMR, autosuggestion and music. Each blend has been carefully crafted to help reduce stress, improve sleep and ease psychological problems.

The history of Receptive Sound Therapy

Receptive Sound Therapy is nothing new, healing with sound is one of the oldest and most natural forms of healing known to man and has been used for hundreds of thousands of years as a way of soothing the mind and emotions.

In the ancient societies of Egypt, Greece and India, the use of sound and music for healing was a highly developed science, and the Aboriginal people of Australia have used the didgeridoo as a healing tool for at least 40,000 years.

In the past 70 years there has been extensive research done on the phenomenon, including the study conducted by Dr. David Trudeau in 1998. He used 18 Hz frequencies to treat patients with chronic fatigue syndrome (CFS) which resulted in patients reporting reduced depression and impulsivity along with increased energy and improved sleep.

Michael Hutchison also mentions this frequency in his book “MegaBrain”, which he says can be used for the purpose of increasing energy and motivation. Dr. Cary Howard also got similar results in his study in 1986, in which 12 students reported significantly reduced symptoms fatigue at the end of a seven-week course.

The techniques used in Receptive Sound Therapy, and in SonicTonic, have been created to bring about quick and long-lasting positive changes. With SonicTonic we address the two main aspects of Receptive Sound Therapy: psychological and neurological. Managing stress, burnout, depression and other conditions often requires a combination of these two approaches. Depression, for example, can be treated most effectively by increasing the release of neurotransmitters in the brain, such as serotonin.

The Neurological Aspect: Brainwave Entrainment

Reading brainwave patterns can tell you a lot about our everyday lives. For example, a person’s brainwave pattern can show if they are tired, full of energy, or feeling focused. Brainwave patterns can also show if someone is suffering with depression, anxiety and a host of other disorders.

Brainwave Entrainment is a technique whereby the brain is coaxed into a certain state through use of pulsing light, sound or electromagnetic fields. Through simple changes and the optimisation of specific frequencies, a huge range of problems can be dramatically reduced or eliminated. For example, memory, concentration, and mental speed can be all improved dramatically thanks to brainwave stimulation. What’s more, sleep and deep stages of meditation can be initiated and headaches can be reduced through brainwave entrainment and it can release helpful chemicals such as growth hormone and serotonin.

The Psychological Aspect: Suggestions, Visualisations and Hypnosis

For problems that can’t be solved by Brainwave Entrainment alone, there are a number of other proven sound-based psychological techniques that can be used. Suggestions (affirmations) and visualisation techniques are great for overcoming anxiety, quitting smoking, losing weight, boosting self-esteem, performance and motivation – and much more.

Hypnosis, for example, is a well-known psychological technique. The task of the hypnotist is primarily to relax the patient to bring his mind into a receptive state (the so-called hypnotic trance). The hypnotist then uses a series of suggestions in the form of sentences or commands, such as, “You are self-confident and self-determined!. When your mind is in a receptive state, suggestions and other psychological techniques (such as visualisations) can have a quick and dramatic effect on your thinking, behaviour and emotional state.

SonicTonic combines sounds that influence brainwaves to help you manage stress, sleep better and focus more, along with autosuggestion that can help put your mind into a receptive state. Why not try out our tonics next time you’re feeling stressed. You’ll be surprised what Receptive Sound Therapy can do for you.

In a study at China’s Peking University, an impressive 75% of study participants reported more restful sleep when exposed to pink noise.
It was discovered that it regulates your brain waves, which is a hallmark of super-restful sleep. A pink noise programme is available for free in the SonicTonic app. Get it here.

Sleep physician Prof. Jürgen Zulley: „Music is monotonous stimulation. And with that you sleep better. I think music is one of the best methods to fall asleep.“

Germany´s most known sleep physician Jürgen Zulley calls music the number one medicine for sleeping disorders. He recommends listening to quite and calming music while its necessary to focus on the sound. He says, that the monotone stimulation is prerequisite for falling asleep and important for it, to be restful. We created different Tonics that trigger these monotonous stimulations and help you with getting a good night sleep.

Compared to 2010, almost twice as many employed people today take sleeping medications

According to the DAK Healthreport 2017, more than twice as many employees take sleeping medication than in 2010. These can negatively affect your health though, causing headaches, sickness or metabolic disturbances. Also, they change the sleep cycles by eliminating the R.E.M. sleep (Rapid Eye Movement), the dream phase, which is extremely important for a mental balance and relaxation.

One in ten workers suffers from particularly severe sleep disorders, so-called insomnia. That’s 60 percent more than in 2010.


The DAK health report 2017 shows that a shockingly high number of 80% of the 18 to 65 year olds says they struggle with falling asleep or sleeping through the night. Especially insomnia, particularly severe sleep disturbances, concerns every tenth employee and can also entail declining concentration and reduced mental performance.

“Sleep disorders can have long-term psychological and physical consequences like depression and confusion of breathing, heartbeat, hormones and other functions.”


Studies have shown that a growing number of people suffers from sleep disturbances, which can severely affect their health in terms of muscle tension, body temperature, metabolism and other functions. According to a study conducted by the University of Warwick and the University College London with 4600 men and women, especially for women the risk of a heart attack increases with a lack of sleep.
