In short: They cannot completely block sound, but they can effectively reduce noise.
Doors are often the weakest link in a soundproofing system. Hollow cores, gaps, and thin surfaces allow sound to easily penetrate. Sound-absorbing panels can improve this, but only in certain areas.
🔊 What benefits do sound-absorbing panels bring to doors?
✔ Reduced echoes and sound reflections
Installing sound-absorbing panels on doors absorbs indoor sound, reducing noise that would otherwise be reflected onto the door.
✔ Improved privacy
By reducing internal reverberation, less sound reaches the door and leaks out.
✔ Quick, aesthetically pleasing, and convenient installation
Sound-absorbing panels—especially wood strip sound-absorbing panels with PET felt—instantly improve soundproofing comfort and aesthetics, even on doors.
🚫 Limitations of soundproofing panels
Soundproofing panels cannot block strong external noise that passes through the door.
To truly achieve sound insulation for your door, you may need:
Door seals
Bottom door seals
Solid door
Soundproofing materials
Combining these materials with soundproofing panels will yield even better results.
