Can a frequency improve your sleep, change your mood, or heal your body? What about the tracks that promise wealth, transformation, or a higher vibration? The numbers sound precise, but the promises often leave out the most important question: what has actually been shown to happen?

In The Frequency Question, Michelle Hoffmann follows sound from vibrating objects through speakers, ears, and the brain. She explores music, binaural beats, medical ultrasound, cymatics, tinnitus, and the power of expectation in language that makes the science approachable. Along the way, she examines why a real benefit from listening does not necessarily prove that a marketed frequency caused it.
