## Questions & Answers

**Q: Are these panels ridged? 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Noise Canceling is Amazing!
*by M***. on July 3, 2018*

OMG! I was amazed when I picked a panel up with the acoustic side near my right ear and it felt like I had my noise canceling headphones on my right ear. All sound on that side was absorbed by the panel – the effect was amazing.I have a small office space which has an echo when I’m on the phone (I really didn’t want people to think I was in the bathroom talking to them on the phone). I put four panels on one wall, and two more on the opposite wall and now it doesn’t sound like I’m on the toilet when I’m on the phone. The panels also help to add a modern decorative accent to my walls (now not only did I get rid of the echo, but I also decorated my office walls).I was initially hesitant to purchase these panels because the images didn’t show much detail such as the fabric weave and quality. Let me assure you that these are very high quality. I took some pictures of the fabric and included it in my review. One thing to note, the colors on Amazon are not accurate for the charcoal and white (the two colors I purchased). The charcoal is much darker (almost black) than the image shows, and the white is a true white (not the light gray color in the Amazon picture).For installation they included mounting brackets but I didn’t want to damage the walls so I used Command brand picture hanging strips (Large Size, 16 lb.). I put six sets of the adhesive strips on each panel (three on the top and three on the bottom), and the panels are held securely to the wall.Shipping was very quick and customer service is amazing. There was a mix up in the shipment of my second order which they resolved immediately. Acoustimac is a trustworthy company with a high-quality product and excellent customer service to back it up. They will be my ‘go to’ company for future acoustic panel needs.The pictures below show the charcoal and white panels on my wall, and a close up of the fabric for each panel.
