Multi-layer composite doors engineered to cut sound transmission without compromising daily usability.

Our acoustic doors use a dense composite core with decoupled steel skins and compression seals on all four edges, including a self-activating drop-down threshold, to achieve high sound transmission class ratings.
Suited for recording studios, broadcast rooms, hospital diagnostic suites, control rooms and any space where sound isolation is a functional requirement.

High mass-per-area core reduces airborne sound transmission.
Automatic threshold seal activates on closing, retracts on opening.
Continuous gasket on all edges eliminates sound leak paths.
Verified sound transmission class ratings up to STC 45+.
Final opening dimensions confirmed and order specification locked.
Door manufactured to spec at our Chennai facility, quality checked.
Packed and transported with frame, hardware and accessories.
Fitted and commissioned by AMT's certified technicians on-site.
Seal and drop-threshold inspection every 12 months.
Depending on configuration, our acoustic doors achieve STC ratings from 35 up to 45+, verified through lab testing.
We use an automatic drop-down seal that activates only when closed, so there's no permanent raised threshold to trip over.
Yes, combined acoustic and fire-rated configurations are available where both requirements apply.
Typically every 3–5 years depending on usage frequency; we recommend annual inspection.
