Acoustic foam serves as a sound-absorbing finishing material in spaces requiring clear, resonant sound devoid of unwanted noise reflections. Its open-cell structure efficiently converts sound energy into heat while absorbing it, while the 3D patterns on its surface partially scatter reflected sound, particularly mid- and high-frequency sounds, resulting in a cleaner and more powerful overall sound.

Specifications for the "Wedge" acoustic foam include:

- Dimensions: 50x50cm / (20 х 20 inches)

Advantages of acoustic polyurethane foam panels over other sound-absorbing materials include:

- High Noise Reduction Coefficient (NRC)
- Lightweight for easy transportation and installation
- Compatibility with various surface types and shapes, as panels are easy to cut to size
- Aesthetically pleasing surface patterns

The variety of profile shapes allows these panels to serve as contemporary wall finishes, providing a professional look to recording studios or home cinema rooms, in addition to their sound-absorbing effect.

Important notes:
- Acoustic foam is supplied compressed to reduce shipping costs. It requires time to regain its original shape once unpacked.
- Unpacking and storing the foam in a warm room expedite the volume restoration process.
- Using a hairdryer at a safe distance can accelerate the restoration process.
- Avoid storing compressed foam for more than 30 days, as it may affect volume restoration.
- Some pores may be larger than others due to the foaming process, but this is normal and doesn't impact performance.
