Sound waves can be measured in phase and amplitude without destroying them. In a sense, the cat stays both alive and dead, and researchers can listen in without opening the box.

The sound waves essentially created microscopic bubbles in the salt solution. Then, when the bubbles collapsed, they created tiny bursts of heat and pressure which triggered a reaction with the glass.

The power of sound reaches far beyond your ears. While you're used to hearing sound through music, voices, or noise, your body is also quietly listening—at the cellular level.
