## Description

MuteX Reduces and Eliminates Sound Transmission!  Reduce or eliminate sound transmitted through walls, floors, and ceilings.  Create a much cleaner sound in studio recording environments.

When MuteX is applied to these products it transforms the noise or vibrating surfaces into low-grade thermal energy. The result is a more quiet and comfortable living environment.  Used in Automotive, Industrial, Commercial, Home Construction for HVAC, Walls, Floors, Ceilings, Doors, Condominiums, Motors, Trunks, Speaker Boxes, Recording Studios, Curtains, etc.
