All acoustical testing was done by Riverbank Testing Laboratories; Intest,
Inc.; Twin City Testing Corporation; or D.L. Adams Associates, LTD. 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 assure the ultimate
designed acoustical performance.
