The world has become a much noisier place, and we frequently encounter decibel levels of up to 70 dB each time we step outside on an average day. Today’s city dwellers have grown so accustomed to ambient noise they can tune out just about anything except the conversation they’re having with the people around them, but even the most focused professionals will tell you that they still need plenty of quiet time to think and work without distractions. Fortunately, our team at National Custom Hollow Metal can manufacture Sound Transmission Control (STC) doors and ship them anywhere in the USA on your schedule.
