Our store offers a curated selection of genuine Japanese products. You can shop with complete peace of mind knowing that all our items are authentic. Please note that the instructions and manual for this product may only be available in Japanese.

1. KEY FEATURES: - Principle of sound absorption and soundproofing: For example, the sound emitted from a porous sound absorbing material is greatly diffused within it, so air vibrations directly transmit the air in the internal bubbles.At this time, viscous friction of the air occurs on the bubble surface, converting some of the sound energy into thermal energy, and it is said that the reflected sound becomes smaller.Sound-absorbing materials have the effect of suppressing the reflection of indoor sound and reducing noise.This is an unpleasant reverberation and noise generated by a special mold that can be used indoors (rooms), and is an essential material for soundproofing.Note Although sound-absorbing materials have a certain soundproofing effect, they can fully demonstrate the professional soundproofing effect, so the soundproofing effect must be combined with soundproofing materials. - Applications: ①. Acoustic adjustment and countermeasures for echo noise for home theaters and vocal music; 2. Used for piano tuning and speaker sound adjustment; ③. As a sound absorbing material for studios, home studios, etc.; ④. Suitable for soundproofing windows and reducing noise.These soundproof panels are versatile, making your office quieter and your audio recordings cleaner.It can also be used in professional studios, playback rooms, concert halls, pitching, churches, home theaters, human voice, home studios, offices, offices, etc. - Environmentally friendly materials and safety This soundproof board is precision-processed, so the ball will not stick even after long periods of use.Because it uses high-density polyester fiber, the sound absorption efficiency and sound absorption coefficient of the sound insulation plate are doubled compared to low-density materials, which can more effectively increase the transmission loss of incident sound.In addition, it is made of environmentally friendly and human-friendly polyester material, so there is almost no odor.Urethane foam has excellent flame retardant properties, and instead of strong flame retardants, we have achieved flame retardancy by using straight flame retardant materials.Affects the human body.Therefore, there is no problem if you paste it in the room where your child lives. - Easy to install: Anyone can set it up!Apply spray adhesive or 3M double-sided tape (not included) to the back of each panel and stick it in place.Note: The polyurethane sponge is shipped in a compressed state, and after opening, it will be left for about 24 to 48 hours and the compression will recover on its own.If there is no recovery effect, soak it in water and dry it, the product will recover quickly. - Satisfied purchase: If the density is insufficient, it cannot be recovered in the compressed state.If you have any problems with the product, such as strange smells, please contact customer service!We will respond quickly and provide a full refund and free replacement to your satisfaction!Please do not give stars.
