Quiet on the Mezzanine

W.A. Schmidt Inc. developed a dampening system for mezzanines for applications where sound and vibration are detrimental. The system was originally created to solve specific acoustic suppression needs of the U.S. Postal Service and the 2004 Republican National Convention.

Working in partnership with a leading national acoustics consultant who specializes in theater and performing arts applications, a new sound suppression system was developed to work with today’s mezzanine construction methods. This proprietary system employs a mezzanine deck comprised of alternating isolated layers of solid, soft and acoustical material. It also utilizes a special fastening system that eliminates the transfer of vibration and sound between layers. In addition, the system incorporates an isolation barrier between beams and columns and between columns and the floor.

The USPS is currently installing ventilation and filtration systems in more than 240 mail distribution centers across the U.S.

A 30,000-square-foot mezzanine at the Republican convention, Madison Square Garden, New York, was raised 9-1/2 feet, while providing noise and vibration suppression that allowed an estimated 15,000 participants to walk the floor as television cameras and sound units reported on the action. A special noise dampening system was employed in the entire structure to isolate sound and vibration on the mezzanine, as well as in the cavity below where vehicles and utilities such as compressors and air conditioning systems operate.
