Scientists Build Acoustic 'Black Hole' That Swallows Sound in Pipes

Researchers adapted cosmic black hole physics to create a device that absorbs sound inside pipes, eliminating echoes and vibrations in ventilation and plumbing systems. The technology mimics an event horizon to trap acoustic energy.

• Device absorbs sound inside pipes, removing echoes and vibrations
• Design is based on adapting cosmic black hole physics
• Target applications include ventilation, plumbing and other enclosed systems
