Foam & Soft — Acoustic Material Guide
Acoustic foam panels are lightweight, open-cell absorbers made from melamine or polyurethane. They excel at mid-to-high frequency absorption and are the most accessible acoustic treatment for studios, broadcast rooms, and home offices. Available in flat, wedge, pyramid, and egg-crate surface profiles that increase effective surface area.
