48 Pack Acoustic Panels Sound Proof Wall Panels High Density Studio Sound Absorbing Material Acoustic Foam Home Decoration

How to quickly return to normal size：

Our sound-absorbing foam are packed using vacuum compression technology，Here are two ways to restore the product.

Natural rebound method :
Step 1.After receiving,take the sound-absorbing foam out of the vacuum packaging and lay it flat in a dry and ventilated environment.

Step 2.Stand and wait: Depending on the thickness, it usually takes 24-48 hours for natural rebound. Thick materials (such as more than 5cm) may take longer.

Step 3.Tap or shake: Pat the surface with your hands or shake it slightly to help the fibers/pores fluff up again.

Heating assisted method:
Step 1.Soak the soundproof foam in water so that each sponge absorbs the water.

Step 2.Then twist the sound-absorbing panel out of the water and blow dry with air or use a hair dryer(40-60℃,distance of more than 20cm).

Step 3.Put them in a sunny and ventilated place to let the sponge absorb heat,giving you the following two methods of recovery.

Question and Answer

Q1: What’s the difference between acoustic foam and soundproofing materials?
A:
Acoustic Foam: Absorbs mid-to-high-frequency sound waves (e.g., voices, music) to reduce echoes and improve sound clarity. Ideal for studios, home theaters, or offices.
Soundproofing Materials: Block noise transmission using dense layers (e.g., mass-loaded vinyl), typically installed in walls/floors.
👉 Pro Tip: Combine acoustic foam with sealing strips for full-spectrum noise control.
Q2: How effective is this foam? What noise reduction can I expect?
A:
Lab Tested: 5cm-thick foam reduces mid-high frequencies by 15-25 dB (e.g., reduces 50dB air conditioner noise to 30dB).
Key Factors: Cover ≥30% of wall area and seal gaps (e.g., doors/windows) for optimal results.
⚠️ Note: Low-frequency noise (e.g., car engines) requires additional damping materials.
Q3: Where can I use acoustic foam?
A:
Home: Bedrooms (block neighbor noise), study rooms, music practice areas.
Commercial: Recording studios, office partitions, podcast rooms.
Avoid: High-moisture areas (e.g., bathrooms) or direct sunlight exposure.
Q4: How do I clean the foam? Is it mold-resistant?
A:
Cleaning: Vacuum dust gently or wipe with a damp cloth (neutral cleanser only).
Mold Prevention: Optional anti-microbial treatment available for humid climates.
Q5: What thickness should I choose?
A:
2-3cm: Basic absorption for small spaces (e.g., cabinets).
5cm: Best for most homes/offices (balance of cost and performance).
10cm: Professional-grade for studios (premium pricing).
Q6: Will the adhesive damage walls?
A:
Removal: Use a hairdryer to warm the adhesive, then peel slowly. Residual glue can be removed with rubbing alcohol.
Compatibility: Works on painted walls, wood, or tiles. Avoid uneven surfaces like raw plaster.
Q7: Can I request custom sizes or colors?
A:
Standard: 50x50cm or 100x100cm (black/white).
Custom Orders: Available for bulk purchases (100+ sq.m). Color customization may incur extra fees.
Q8: How is the foam packaged for shipping? Will it get crushed?
A:
Vacuum-Sealed Packaging:
The foam is compressed and vacuum-packed to minimize shipping volume and prevent deformation.
Simply open the package, allow 24-48 hours for the foam to fully expand to its original thickness.
