SONICMAZE! Decorative Acoustic Panel Art: Sound Absorbing Lightweight & Micro-Perforated (3 x 3 panels, DIY fast installation)

These acoustic panels are a little pricey, true, but they do provide amazing sound-dampening, and they look GREAT. They really are super-lightweight, and the installation is ridiculously quick and simple. For musicians or other audio / recording professionals, or for corporate spaces with a lot of echoing hard surfaces, I recommend them highly.

I bought this for my office. The installation is very simple, taking about 10-20 minutes. It works very well blocking noises.
