Almost nobody who sells sound, or practices it, has read the numbers beyond what ranks highest on google or has the most citations, and publicly accesible AI models and research tools hallucinate. That's why we made this.

This report is the numbers. We took the 8,619 sound studies and 6,209 vibration studies in the MEMRA record (100k+ studies, papers, and texts) and sorted them by the route the energy took into the body: through the ear, through the floor, through the hand, through a seat, through a bed... and turned it into insights. Audible music carries 1,472 randomized trials. Standing platforms carry 614. Seated and contact-coupled instruments carry 17. Beds and tables carry 8. The trial a vendor quotes you for a transducer bed was, in all likelihood, run on a listener in a chair with the speaker across the room, and this record identifies and notes the distinction.

Inside: a frequency census from the 2,396 studies that named the frequency used, by band and in five-hertz bins (30 and 40 Hz hold the mass; 75 to 80 Hz holds 163 studies, 40 of them in people); the direction of 56,533 extracted claims for anxiety, pain, sleep, stress, cortisol and blood pressure, favorable, unfavorable and null, each with the sentence it came from; where 40 Hz and binaural beats actually stand; the singing bowl record, all 24 studies from it; vibroacoustic therapy as Olav Skille defined it in 1982 and the 147 studies since; the exposure limits for a room with the gain turned up, in decibels and metres per second squared, with the standards that set them; six questions to ask before you buy an instrument; the market estimates, labelled by source and by how much to trust them; and 98 records at the back, each with the DOI record.
