Resonance

Science and Physics

In short, yes—but only under very specific conditions that are rare in everyday life. Shattering glass with your voice requires matching the glass’s resonant frequency with...

Science and Engineering

Under everyday conditions, a human voice cannot break ordinary glass. Cracking or shattering glass with sound requires matching the glass’s natural resonant frequency with eno...

Science & Physics

Sound can break glass when the pressure variations from a loud enough tone match the glass’s natural resonant frequency, concentrating energy into the material. At resonance,...
