Abstract: An acoustic system is disclosed. The acoustic system includes a sound absorptive substrate, and a rigid polyester shell configured to be positioned over the sound absorptive substrate. The rigid polyester shell is configured to be mounted on an interior surface of a building such that at least some sound waves pass through the rigid polyester shell. The shell is configured to provide aesthetic features to the acoustic system.

Abstract: An acoustic system is disclosed. The acoustic system includes a number of acoustic panel sections having a variety of acoustic properties. Each acoustic panel section is configured to be mounted on an interior surface of a building and cooperates with the other acoustic panel sections to define a pattern on the interior surface of the building.

Abstract: A foam-type acoustic panel is designed to be mountable on a stand having a shaft. The acoustic panel includes a main body portion. The main body portion has a first end, a second end, a front surface, a rear surface, a top surface, a bottom surface, and first and second interlocking members. The first and second interlocking members define a multi-segment cut that extends between the top and bottom surface. The multi-segment cut includes a first end disposed at one of the front and rear surfaces, and a second end disposed interiorly of the other of the front and rear surfaces. The second end of the multi-segment cut defines an elongated aperture extending between the top and bottom surface for receiving a shaft of a stand.
