Sound Attenuation

Noise Reduction Door Systems - Interior Doors

Our major supplier for commercial and architectural flush doors - Lynden Door - offers a good range of Sound Transmission Class (STC) Rated Doors.

Sound Transmission Class (STC) rated doors are regulated and administered in a manner similar to fire doors. That is, door core manufacturers are required to submit cores for a test and once they have passed that test, may license fabricators like Lynden Door to produce acoustical doors under manufacturer test auspices.

Applications calling for STC doors and accessories include:

• health care: hospitals and medical buildings
• hospitality: suite entries, adjoining room entries
• commercial: executive offices and meeting rooms, police stations, recording studios, radio & TV production stations
• education: classrooms, lecture theatres, offices
