Seal Door for Noise in a nutshell
If you’re under a flight path, near a busy road, or dealing with constant external noise, even small gaps around your door can let a surprising amount of sound in. Sound travels through air - and gaps around your door act like open channels.
Seal the gaps, and you reduce the pathways that noise uses to enter your home. Be aware: this won’t completely soundproof your home. But it can noticeably reduce sharp, intrusive noise - especially when combined with other upgrades like window protection and acoustic insulation.
