24 pieces of acoustic foam acoustic panels with self-adhesive backing, sound insulation for walls, 30x30x3cm foam panels, suitable for offices and recording studios

🎵【Soundproofing】- Improve the acoustics of your room with our foam mat that absorbs sound reflections and efficiently reduces wall noise. This pack of 24 soundproofing wedges provides a neutral sound environment that relaxes you from the inside out. 🎵【NO MORE ECHOS】- Made of fire-resistant acoustic foam mats, they provide good sound insulation for your walls. And not only that: these soundproofing also efficiently reduce flutter echoes, reverberation, slapback, and room rings, creating an acoustic environment. 🎵【MULTIPLE APPLICATIONS】- With dimensions of 12 x 12 x 3cm, these pyramid foam soundproofing panels can be used in studios, recording booths, cinemas, concert halls, churches, and control rooms. For a perfect acoustic effect, you can use more than one panel. 🎵【Improved Self-Adhesive Acoustic Foam】- Acoustic foam is equipped with a self-adhesive back and can easily support up to 3.9 pounds without worrying about it falling off. The high-quality adhesive tape helps in mounting the panels on walls and ceilings for soundproofing. 🎵【Attention】- To reduce shipping costs for foam panels, we rely on strong compression packaging. However, it may take some time for the panels to recover from their dense packaging. If some panels do not fully expand within 24-48 hours, soak them briefly in water and squeeze them dry. The sound absorber will then recover quickly and completely.
