I'm thinking of standing them up between my desk and the filing cabinet in front of my desk w/ 18" frestanding.** A: I'm not sure what ridged means, but they are just square edged, flat, 4 inch thick panels. No way to stand them on edge unless you rig something up. **Q: Which material is used inside the panels?** A: Hello, Our panels are typically made using Roxul Rockboard insulation. However, we do have Owens Corning 703 and our all recycled product Eco-Core. Let me know if you have any more questions. -Eric Harris **Q: We purchased 10 of these tiles form you back in November. Is there a suggested height to hang them?Would heights that vary be beneficial?** A: place them with center at ear height and try some randomness also. try googling the mirror method of placing wall treatments. **Q: I have a pretty small office/studio (10*11) how many of these will I need?** A: i ordered 3 in one of our conference rooms about the same size as your studio. It reduce the noise by about 35 percent. I really like them I am planning on ordering 3 more for the same room.We an open concept design so our space has no ceiling and noise bouncing off the walls, floors made it unbearable. The 3 panels we put up made a huge difference. I am planning on adding 3 more to the same conference room and purchasing more for the other 3 conference rooms we have. I would say between 6/8 panels would work just depends on percentage of noise you would like to lessen. ## Frequently Bought Together - Acoustimac Sound Absorbing Acoustic Panel DMD 4' x 2' x 2" STONE - UMIACOUSTICS 6 PCS Sound Proof Panels,47.2 x 23.6 Inches Sound Absorbing Panels,Decorative Acoustic Panels in Art Curve Shaped Light Tan Color - Foroomaco 4 Pack Bass Traps for Ceiling Corner 16.5" Triangle 12" Depth Triangular Pyramid Acoustic Foam Bass Trap Sound Proofing for Home Studio Booth Low to High Frequency Sound Absorption Foam --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/502749854-acoustimac-sound-absorbing-acoustic-panel-dmd-4-x-2-x](https://www.desertcart.us/products/502749854-acoustimac-sound-absorbing-acoustic-panel-dmd-4-x-2-x) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-21*
