We go on an exploration of the somewhat recent trend of trying to heal, calm, or “raise the vibrations” of human beings by means of sound therapy. While sound does have some real medical applications, there’s also a concert of woo awaiting the unwary consumer. From singing bowls to tuning forks, it’s a web of conflicting benefits, sketchy profit streams, and turgid pseudoscientific jargon that made even Ben’s head hurt a little. (But we played some harmonic vibrations to raise his energy and he feels better now.)
