Welcome! to STC Sound Control

Sound Control for Every Situation!
Most of the time, we ignore sound until it becomes a problem. But once it does, it’s often a big one. From hospitals and dormitories to restaurants and office spaces, noise can affect productivity, customer satisfaction and overall success. Whether it’s sound that’s finding its way between rooms, lingering within one room or traveling between floors to the space below, we create noise reduction solutions to make complaints and inconvenience a thing of the past.

STC’s unique noise control products are simple, cost-effective and high performing for developers and architects. And perhaps more importantly, they help customers’ and end-users’ acoustical comfort-fixing issues from complaining hotel guests to office workers desperate for a little privacy.
