SOUND TEST INFORMATION
All acoustical testing was done by Riverbank Testing Laboratories; Intest, Inc.; Twin City Testing Corporation; D.L. Adams Associates, Ltd.; Veneklasen Associates; or NGC Laboratories. For type of floor covering used, channel spacing and other information, contact Maxxon for test reports by number. For good acoustical performance, the selection of a floor/ceiling system attaining a minimum 60 STC and IIC is recommended. Systems attaining ratings less than 55 STC and IIC provide only marginal acoustical performance. The Maxxon floor underlayments and Acousti-Mat are but single components of an effective sound control system. No sound control system is better than its weakest component. Care must be taken in the installation of all components of construction to ensure the ultimate designed acoustical performance.
