The gymnasium at Ichabod Crane suffered from poor acoustics and an aged sound system. Based on field design, AVL determined that a new sound system by itself would not provide adequate results; the acoustics had to be addressed. Beyond the overall high reverberation time, there were specific echoes caused by the barrel vaulted shape. The barrel vaulted space was covered in Homasote panels which had been painted several times. This effectively negated the small amount of absorption the Homasote provided. There was not budget to completely remove the Homasote so we decided to treat the curve specific echo areas. Utilizing a high NRC Epic ER3.5A roof deck material installed in a novel manner, we were able to control reverberation and echoes. This fix combined with a sound system design that minimized activation of the remaining Homasote areas results in a highly intelligible sound. Cosmetic upgrades included in the project finished the space with a more modern appearance.
