Acoustic panels and soundproof curtains serve different purposes while offering effective solutions for sound control. Acoustic panels focus on improving sound quality, while soundproof curtains are designed to block sound from entering or leaving a room.

Acoustic wall panels will come in thicknesses of either 2″ or 4″. While traditional wisdom states that thicker is better, 2″ panels are considered the industry standard by many. They will not be able to absorb frequencies as low as 4″ panels, but that's OK.

Commonly, acoustic panels are made from a timber frame with varying layers of acoustic foam. Foam is the best material to use for an acoustic panel because it completely absorbs frequencies on the surface, so you get a resonance happening inside the cavity. Therefore, above the cavity, you get noise cancellation.
