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.

New 12pcs Bundle Hemisphere Grid Adhesive Backed Type Acoustic Panels Sound Absorption Studio Soundproof Foam 7 Colors KK1056

Sound stuff is goood.

Works well. You can tell the difference in sound reflections. I am happy with it. Makes the room more solid sounding i guess. Not so much echo. I would use this in every room if i could just to make the house sound nice and consistent.

Really works.

They really do work. My use case may be unusual but it definitely helped. I lined the inside of a large cardboard box with these and cut the box to fit around the motor of my bicycle trainer. It can be rather loud. Having these surrounding the motor made a huge difference. It was noticeable to the ear and I also used a sound meter app on my phone to verify that it wasn't my imagination. They are easy to cut to whatever shape you need and are lightweight.


I love these. They absolutely get the job done for a fraction of the price that these panels would usually cost. They stop all echoing within my room to allow for a crisp, clear recording quality.

Amazingly fast shipping, no damages!

It honestly felt like an order for prime users, it came very fast! No damages, and very compact. Thank you!
