Author: Lynn Leffler  |  Last update: Friday, June 5, 2026

The key to soundproofing your existing wall is a layering system that forces soundwaves & vibrational energy to collapse. Layer 1 is a limp sheet of dense mass called dB-Bloc. Staple it right to your existing wall ensuring 100% surface coverage. Layer 2 is a set of RSIC Retro Clips and furring channel.

Is it possible to 100% soundproof a room?

Is there a sound that cancels out other sounds?

Noise canceling, also known as noise cancellation is a technology used in headphones and earbuds to actively cancel out external sounds by generating an opposing sound wave. This opposing sound wave, also known as anti-noise, effectively cancels out the external noise before it reaches the listener's ears.
