What Is Sound Therapy Or Sound Healing
Sound therapy is a form of alternative medicine that utilizes sound waves to promote healing and balance for the body mind and spirit. Sound healing is a growing field that has gained recognition and popularity in recent years. One of the instruments used in sound healing is the singing bowl also known as a sound bowl, which has been known to produce soothing and calming vibrations. There is a good reason why sound bowls are so popular. In this article, we will check out one of the applications of sound bowls in a therapeutic session.
Sound therapy is effective in treating depression, anxiety, pain management, improving sleep, boosting the immune system, and promoting overall well-being.
It is based on the principles of psychoacoustics, the study of the psychological and physiological effects of sound on human beings, and brain entrainment.
Brainwave entrainment is the process by which external stimuli, such as sound, light, or vibration, influence the brain's electrical activity. This influence can result in changes to the brain's state of consciousness, such as increased relaxation, improved sleep, and reduced stress and anxiety.
The basic idea behind brainwave entrainment is that when the brain is exposed to rhythmic stimuli, such as a repetitive sound, it will naturally start to synchronize its own electrical activity with that rhythm, leading to a change in brainwave patterns.
One of the most well-known forms of brainwave entrainment is binaural beats, which is the phenomenon of two different sound frequencies being perceived as a single tone when played in each ear.
When the difference between the two frequencies is in the range of 1 to 30 Hz, this difference is said to be audible as a “beat.” The frequency of the beat corresponds to a specific brainwave state, such as alpha (8-12 Hz), beta (13-30 Hz), or delta (0.5-4 Hz). By listening to binaural beats, the brain can be entrained to these specific brainwave states, which can result in changes to mood, cognition, and overall well-being.
Singing Bowls for Sound Therapy
Singing bowls produce specific frequencies and rhythms that can be used to entrain the brain and produce desired effects, such as relaxation, improved focus, and concentration, and reduced stress and anxiety.
One of the most common techniques is the use of a headset of three singing bowls, which are placed around the head area, left, right, and crown. This headset can be used to produce binaural beats through the interaction of the different tones of each bowl. To achieve this, it is important to select singing bowls with the right properties, such as fundamental tones that are not too high, a slow pulse, and a long-sustaining sound.
In this article, I will delve into the use of singing bowls in sound therapy, specifically their use in creating a headset for brainwave entrainment.
Singing Bowls For The Head
A headset is a set of three singing bowls placed around the head area - on the left, right, and crown. This setup is commonly used by sound healing practitioners, and it is believed to have something to do with the Third Eye Chakra and the Crown Chakra. However, the primary reason for using a headset of singing bowls is for brainwave entrainment.
To create an effective headset, certain criteria must be followed when selecting the singing bowls. Here are some of the important considerations:
- The fundamental tone of each bowl should not be higher than one of the fourth-octave notes. The ideal fundamental tone is in the third octave as low tones are more effective for relaxation. However, tones that are too low, such as the second-octave fundamentals, may carry dark characteristics or be too grounding.
- The pulse of each bowl should be slow. Ideally, you want to hear the systematic communication between the three members of the set. Too many overlapping beats can be distracting, except for people with Attention Deficit Disorder (ADD).
- At least one tone of each bowl should create the binaural beat effect with the tones of the other two bowls. For example, the first overtone of the left ear bowl can be 450Hz, the first overtone of the right ear bowl can be 455Hz, and the first overtone of the crown bowl can be 460Hz or 445Hz.
- All three bowls should have the same complexity of sound. They should be close to each other in terms of character and "mood".
FAQs
What is sound therapy?
Sound therapy is a form of holistic healing that uses sound waves—often from instruments like singing bowls, gongs, or binaural beats—to promote relaxation, reduce stress, and support mental, emotional, and physical well-being. It works by influencing the brain, nervous system, and body through vibrations and rhythmic patterns.
What is the difference between sound healing and sound therapy?
While the terms are often used interchangeably, sound therapy is typically associated with evidence-informed practices that integrate principles of psychoacoustics and neuroscience. Sound healing may carry a more spiritual or metaphysical connotation, emphasizing transformation, energy balance, or chakra alignment. Both aim to restore harmony within the individual.
How does sound therapy help with anxiety, depression, and sleep?
Sound therapy can entrain the brain into states of relaxation by using rhythmic frequencies. Techniques like brainwave entrainment and binaural beats help the brain synchronize with calming patterns, reducing stress hormones and promoting better sleep, emotional regulation, and cognitive clarity.
What is brainwave entrainment and how is it used in sound healing?
Brainwave entrainment is the process of using rhythmic auditory stimuli—such as tones, pulses, or repetitive sound patterns—to guide the brain into specific brainwave states. For example, delta waves (0.5–4 Hz) support deep sleep, while alpha waves (8–12 Hz) promote calm focus. Singing bowls and binaural beats are commonly used to achieve this effect.
What are binaural beats and how do they work?
Binaural beats occur when two tones of slightly different frequencies are played in each ear. The brain perceives a third "beat" corresponding to the difference between the two frequencies. This beat can entrain brainwaves to states associated with relaxation, creativity, or focus, depending on the frequency range.
How are singing bowls used in sound therapy?
Singing bowls—especially Himalayan singing bowls—are prized for their rich overtones and long sustain. They produce rhythmic fluctuations (monaural beats) that can entrain the brain, calm the nervous system, and create a meditative state. They’re often used in individual sessions, group sound baths, or meditation practices.
What is a singing bowl headset in sound therapy?
A singing bowl headset is a set of three bowls strategically placed around the head: one near each ear and one near the crown. When played in specific sequence, the differing tones can create binaural beats and complex pulsations that promote brainwave entrainment and deep relaxation.
What kind of singing bowls are best for creating a headset?
The ideal headset uses bowls with fundamental tones in the third or fourth octave—not too high to disturb, and not too low to become overly grounding. The bowls should share similar tone quality and sustain, with at least one overtone in each bowl close enough to interact and create a binaural beat with the others.
Can sound therapy work for people with ADHD or sensory issues?
Yes—some individuals with Attention Deficit Disorder (ADD) may actually benefit from more complex and overlapping pulses, which can help their brains stay engaged. A skilled sound practitioner can tailor the soundscape to suit individual neurological and sensory profiles.
Is sound therapy scientifically proven?
Elements of sound therapy—such as brainwave entrainment, music therapy, and the calming effects of rhythmic sound—are supported by scientific research. While not all claims in the sound healing field are evidence-based, many aspects have been validated by neuroscience, psychoacoustics, and clinical studies in stress reduction and pain management.
