Built-In Vibration Control to Soundproof Spaces

Researchers have determined how built-in resonators handle vibrations under a variety of scenarios. Resonators are devices that help manage vibrations — some vehicles have them to limit the sound emitted from a car’s muffler and some bridges and buildings use them to limit noise and movement from those structures. Resonators use spring-like oscillation to control and change vibrations — some absorb and neutralize them while others amplify and direct them to specific places.
