The Science
Introduction
Research has shown us that sound therapy and sound meditation might be able to help with anxiety,, depression,, stress,, fatigue,, chronic pain,, cognition and memory and overall mental and spiritual wellbeing. There is some evidence that it might even work for specific medical conditions. This page provides an overview of peer reviewed academic research of the effects of sound therapy.
Eastern approaches
Eastern integrative medicine includes centuries-old practices and treatments which have recently garnered significant attention in the west. Many traditional medicine techniques such as yoga, sound therapy and meditation, Qigong, Tai Chi Chuan, and acupuncture have recently been studied in relation to their potential for reduction of human chronic stress [1], a widespread societal health problem.
Singing bowl sound meditation is an ancient practice that has been used for centuries in Tibetan and Buddhist cultures as a form of healing and relaxation. Over the years, several studies explored the effects of singing bowl sound meditation on mood, tension, and wellbeing. The reasons behind the positive effects of singing bowl sound healings are not fully understood. Possible explanations include alterations in brain waves, binaural beats, and the vibrations of singing bowls interacting with the energy field surrounding the human body, known as the biofield. Studies have shown that singing bowl sound meditation can produce physiological and psychological responses, reducing negative affect and increasing positive affect, as well as improving blood pressure, heart rate, and respiratory rate. Singing bowl sound meditation may be an effective low-cost and low-technology intervention for reducing feelings of tension, anxiety, and depression while promoting spiritual well-being. [2]
Anxiety and depression
Background major depressive disorder (MDD) is a persistent worldwide psychiatric condition. In this study, the findings suggested a significant clinical improvement during sound therapy in patients with MDD. [3]
One study published in the Journal of Evidence-Based Integrative Medicine found that an hour-long sound meditation helped people reduce tension, anger, fatigue, anxiety, and depression while increasing a sense of spiritual wellbeing. [4]
An earlier research study linked sound therapy with short-term improvements in objective and subjective cognitive function as well as mental health and spirituality. [5]
Fibromylagia
There is potential to use soundwaves even for specific conditions like, fibromyalgia [8] [9] where it showed statistically and clinically relevant improvement.
Unlike in meditation or yoga, participants do not need to have any experience in meditation or practice. Sound meditation or therapy may be especially useful in decreasing tension in individuals who have not previously practised this form of meditation. [10]
How could it work?
Music is a collection of soundwaves, a universal language that can produce profound emotional and cognitive responses. It engages a diverse network of brain regions and circuits. There is increasing evidence how music and sound therapy can be used to retrain impaired brain circuits in different disorders. [11]
A review[12] of the available research literature in 2021 pointed to the positive effects on physiology by narrowing music to sound and sound to vibration. Basic physiological mechanisms include stimulating neurological effects like protein kinases activation, nerve stimulation and musculoskeletal effects including muscle stretch reflex, anabolic effects on the spine.
Here is a detailed PhD study [13] how this may work on a neurological level.
Musical theory research
Specific sound therapeutical approaches have been developed to take advantage of the development in musical knowledge and theory. Music theorists [14] have shown that lower or higher pitches of sounds and musical chords progression can have a significant impact emotionally. Dissonant sounds, for example, might have a more tense, unstable effect while more harmonic sounds will have a more overall relaxing ‘happiness’ inducing effect. [14]
Linked to this is emergent research into spatial sound that provides a new field of study that may further the understanding of the principles of sound and how to make use of its potential effects on human wellbeing. Spatial coherence (the process of mapping soundwaves to geometrically designed acoustic chambers) of soundwaves may have a distinct effect on harnessing energy in natural (bio) organisms, such as improved homeostasis in the human body.
It may help restore, maintain and optimise balance in cell organisms, implying potential applications for treatment and prevention of pathological conditions associated with disease and trauma. [15]
Altered states of consciousness
Here [16] is a video by a neuroscientist that explains what effect altered states of consciousness have on human beings and why this might be useful.
