Arrowzoom Acoustic Self-Adhesive Hemisphere Grid Description & Complete Guide
Arrowzoom Self-Adhesive Acoustic Hemisphere Grid Foam comes with adhesive tape at the back of each Tile. Hemisphere Grid can soundproof sonic sound with the aesthetic grid. It was invented with the aim of reducing echoes and improving sound quality.
ÂWhy Should You Install Acoustic Self-Adhesive Hemisphere Grid Foam?
- Effective in reducing noise that it’s even used for many firearm shooting ranges
- Unlike the Pyramid Tile, the hemisphere grid will reflect the sound less, and absorb more. The reflected sound will be directed in various directions.
Features & Highlights of Acoustic Self-Adhesive Hemisphere Grid Foam:
✅ High density
Acoustic cell structure is designed to maximize noise absorption.
✅ Easy to install
Self-Adhesive. Easy to cut and fit.
✅ Non-Toxic
All our acoustic panels are non-toxic and environment friendly
✅ Amazing Material
The high quality acoustic panel are designed by audio engineers that allows anyone who like to improve the sound quality or solve sound issues to save time. Best sound deadening to filter approximately most of the outside noise from entering the room.
✅ Improve Acoustic Quality
By controlling the sound reflections using absorption panels, you can concentrate on the sound that you would like to hear. Speech intelligibility is particularly critical for effective communication.

Technical Data Sheet
STC (Sound Transmission Class), is a numerical rating of how effective a material is at blocking the transmission of sound through itself. This rating generally applies to hard materials like rubberized sound barriers, concrete, brick and drywall but also applies to a much lesser degree to softer materials like mineral fiber (although it isn’t tested by itself; it’s tested as part of a wall system to verify its effectiveness).
 
How To Install Self-Adhesive Acoustic Panel Step by Step
Follow the guidelines below to install acoustic panels to your walls step by step.
Step 1: Restore Vacuumed Acoustical Treatment Foam
Follow the instruction in this video to extract the acoustic foam
Step 2: Locate the Acoustic Foam For Outline
Lay the Foam out for your specific application. Keep in mind that you want the foam evenly distributed throughout the room.
Step 3: Mark & Resize the Acoustic Foam To Best Fit
Measure the designated areas that need to be field cut on the foam and make the appropriate cuts (examples would be around beams, doorways, or if a short piece is needed). After all the pieces have been field cut, put the material back in the appropriate position on the wall or ceiling and lightly mark the bottom and side of where each piece will be lightly with a pencil to ensure straight application.
Step 4: Remove The Adhesive Paper And Stick The Acoustic Foam
Slowly peel off the adhesive paper and hang the insulation mat on the designated surface. Once you peel off the sticker, the Acoustic foam should easily stick to the surface of your choice. Remove all the air bubbles from underneath by flattening them with your hands.
Step 5: Hang the Acoustic Foam With The Marked Line
Line up the materials on marked lines from Step 3 and press firmly against the material compressing the foam. Repeat step for remaining pieces of foam.
