Soundproofing - Is It Possible To Soundproof Anything?

We hate to be the bearers of bad news, but here it is: it’s not possible to completely soundproof anything. The best achievable outcome is a significant reduction in the noise you’re trying to block, not total elimination. “Sound” is a broad term that varies by frequency, intensity, and source. “Soundproof,” however, has a very specific meaning: to prevent the passage of sound entirely. In reality, that level of control simply isn’t achievable in most situations.

For example, you can soundproof against a casual conversation through a wall; the sound range is narrow, volume is low, and it’s primarily airborne noise, which is relatively easy to control. But can you soundproof a ceiling from a rock band playing upstairs? Highly unlikely. The sound covers a wide frequency range, travels through multiple structural paths (walls, floors, HVAC, outlets, plumbing), and includes impact noise from drums and bass that’s extremely difficult to isolate. The term “soundproofing” is really a misnomer that’s persisted over time; much like “sound board,” the fiberboard sold at hardware stores that offers little to no acoustic benefit. Reputable sound control manufacturers typically avoid the word “soundproof,” while online retailers often use it for marketing. The problem is that it sets unrealistic expectations. Implying complete isolation from all noise through any surface, which physics simply won’t allow.

At IsoStore, we avoid the word whenever possible because it’s inaccurate. Still, we use it occasionally since many customers search for it when looking for sound control solutions. Please remember: no company sells true soundproofing products. You can’t fully stop sound transmission through any wall, ceiling, floor, window, door, or car surface. However, with the right materials and installation, you can achieve major reductions in sound transfer and even make certain frequencies inaudible. More accurate terms include sound abatement, sound control, sound reduction, and sound mitigation. Using these terms in your research will lead you to realistic, physics-based solutions, and help you avoid the misleading promise of “soundproofing.”
