You are likely thinking of (Poliquin’s method) or confusing him with Pavel Tsatsouline (vibration training) or general acoustic engineering.
(d. 2018) was a renowned strength coach known for German Volume Training , metabolic typing, and biofeedback printing. He did not publish any significant work on "sound vibration dampening." charles poliquin sound vibration dampening
However, since you asked for a "proper guide" on , the closest legitimate concept in his work is Auditory Biofeedback for Motor Learning . Here is the proper guide based on Poliquin’s actual published principles. The Proper Guide: Charles Poliquin’s Use of Sound & Vibration Dampening 1. The Core Principle (Poliquin’s Actual View) Poliquin argued that external noise and vibration are "neural noise" that degrade motor unit recruitment. He used sound dampening (earplugs, noise-canceling headphones) not for hearing protection, but to increase proprioception (awareness of body position).

After 4 weeks of this, athletes improved lifting technique without visual/verbal coaching. 3. Vibration Dampening (Not Whole-Body Vibration) Poliquin was against whole-body vibration platforms (Power Plate). He called them "neurological confetti." He did not publish any significant work on
