This tool helps builders visualize the difference between a standard “echo box” wall and a properly soundproofed assembly. It demonstrates two key physics concepts: Mass (using dense Rockwool instead of light fiberglass) and Decoupling (using Resilient Channel to break the vibration path so sound can’t travel through the studs).
It includes a “Noise Dampening Visualizer” that shows sound waves trying to penetrate your wall, illustrating how each layer strips away decibels before they reach your ears.

Rockwool vs. Fiberglass & The Magic of Resilient Channel.
1. Noise Source
2. Wall Assembly
Rockwool is 3x denser than fiberglass.
The Two Principles of Silence
Sound is energy. To stop it, you need heavy, dense material to absorb that energy. Rockwool (Mineral Wool) is about 3x denser than standard fiberglass. It absorbs mid-to-high frequencies (traffic hiss, voices) far better than foam or fiberglass.
Low frequency noise (thunder, engine rumble, bass) travels through solid studs like electricity. Resilient Channel is a springy metal strip that separates the drywall from the studs. It breaks the vibration path, stopping sound from jumping from the outside wall to the inside wall.
