Whats the best way to diy soundproof a room?
Start by checking the areas around the windows, doors, and electrical outlets. Are they properly sealed? If not, you’ll need to get some acoustical caulk like quietseal and fill in the cracks.
Are your doors hollow or solid? Try replacing hollow doors with stronger, solid doors to help block sound and seal all the gaps with Weatherstrips.
Finally, you’ll use a series of techniques to add damping compound and drywall or quietrock to the walls and ceilings. Apply the damping compound to your existing surface (as it is), screw the new drywall over top, and fill in the seams with acoustical caulk and repaint.

The eggcrate method is actually not very good, I’ve done it. All it does is soak up the high frequencies, resulting in a muffled sounding room. It’s actually counterproductive (as far as keeping your noise from bothering others, because the muffled sound will make you turn up the sound to hear it better. It all depends on what you’re trying to do, how much time, work and money you want to put into it. You’re trying to do one or both of these things: 1. Keep extraneous noise from getting in. 2. Keeping the noise you’re making, from getting out. Most people want to do both. OK, now for the acoustics lesson: High frequencies (treble) don’t have much energy, so can be blocked and/or absorbed easily. Low frequencies (bass) have a lot of energy, so they can go through walls and other materials very easily. That’s why when some moron with his car stereo is driving around you hear all the bass, but little or none of the high frequencies. Only very dense materials block low frequencies. Like co
