General Physical and Emotional Well-being
Many scientific studies, including the study in vibroacoustic therapy, show that low- frequency sound waves have potential in helping general well-being. The studies have shown that sound is able to help with stress release[i], tiredness[ii], anxiety[iii], muscle strain[iv], and can help release pain[v]. It has also been shown that it is able to help with emotional and physical relaxation[vi], can help increase awareness of one’s own physical and emotional sensations[vii], can improve concentration[viii], promote sense of peace and clarity[ix] and help with self-reflection[x], confidence[xi], creativity[xii]; is able to increase sensations of being hopeful[xiii], powerful[xiv], valuable[xv], optimistic[xvi], cheerful[xvii], energetic[xviii], joyful[xix] and thoughtful[xx]; can also assist in coping with feelings[xxi], help focus[xxii], coping and management skills[xxiii]; and has potential in promoting overall well-being[xxiv]. “Many research participants stated that they would have benefited in having more sessions and more frequently”[xxv].
Parkinson’s Disease
A study showed that the sound treatment resulted into “25% and 24% improvement in reducing tremor and rigidity scores with participants who had Parkinson’s disease”[xxvi].
Sleep Disorders
Sound can potentially help with acute and chronic sleep disorders. See more at Wang CF, Sun YL, Zang HX. Music therapy improves sleep quality in acute and chronic sleep disorders: a meta-analysis of 10 randomized studies. International Journal of Nursing Studies 2013; 51(1): 51-62.
Autism Spectrum Disorder

Other scientific studies have also shown that sound might be able to help with Autism Spectrum Disorder by decreasing stereotypical and self-injurious behaviour[xxvii].
Schizophrenia and Schizophrenia-like Disorders
“There is evidence that music therapy, as an addition to standard care, can help people with schizophrenia improve their global state, negative symptoms, depression, anxiety, and social functioning over the short- to medium-term”. See more at Mössler K, Chen X, Heldal TO, Gold C. Music therapy for people with schizophrenia and schizophrenia-like disorders. Cochrane Database of Systematic Reviews 2011, Issue 12. Art. No.: CD004025. DOI: 10.1002/14651858.CD004025.pub3.
Acquired Brain Injury
“The results of two studies included in this review suggest that rhythmic auditory stimulation may help improve gait velocity, cadence, stride length and stride symmetry in stroke patients”. Bradt J, Magee WL, Dileo C, Wheeler BL, McGilloway E. Music therapy for acquired brain injury. Cochrane Database of Systematic Reviews 2010, Issue 7. Art. No.: CD006787. DOI: 10.1002/14651858.CD006787.pub2.
Meditation and an Increase in the Grey-matter Density in the Hippocampus
Harvard study in meditation has shown that the meditators experienced the “increased gray-matter density in the hippocampus, known to be important for learning and memory, and in structures associated with self-awareness, compassion, and introspection”, as well as decreased grey-matter density in amygdala, “which is known to play an important role in anxiety and stress”, http://news.harvard.edu/gazette/story/2011/01/eight-weeks-to-a-better-brain/.
Sound bathing — “which “bathes” you in the sound of music — claims to [potentially be able to] shift the brain from Beta (waking state) to Theta or Delta (meditation) through the vibrations of the instrument”[xxviii], which effectively makes it a type of “noisy” meditations. The only difference is that, unlike with conventional meditation techniques, you don’t actually have to do anything during the gong bath – just lay down and relax while listening to the sounds. The sound will do all the work for you. Hence, sound bathing can also be called “lazy” meditation.
