Do soundproof paints work as the companies claim?
Yes, the soundproof paints indeed work as claimed.
Are they effective as a soundproof solution?
Here’s the thing, if your concerns are faint noises (like murmurings) or low-level sounds, then soundproof paints really do make a difference. They do dampen those kinds of noises by 30%.
But if you’re soundproofing against shouting, close traffic noises, loud sounds, vibrations, and others, you would be disappointed. Instead, you should use more effective soundproofing solutions like soundproof foam and soundproof curtains.
