Acoustic Doors for Hospitals, Hotels and Offices
An acoustic door is a sealed, dense door assembly engineered to reduce sound transmission between two spaces. It is the door equivalent of an acoustic wall — and it only performs as well as its weakest seal.
Understanding Rw / STC ratings
Rw (and the related STC value) is a single-number rating of how much airborne sound a door blocks across speech frequencies. Common project targets are Rw 32 (light office privacy), Rw 38 (hotel rooms), Rw 42 (conference / consultation rooms) and Rw 45+ (studios, auditoria).
What makes an acoustic door work
Mass + sealing. A dense composite or steel-faced leaf provides the mass; a multi-stage perimeter seal plus an automatic drop-seal closes the gaps that otherwise leak sound.
Where acoustic doors are used
Hospitals (ICUs, consultation rooms), hotels (room entrances and banquet halls), offices (boardrooms), educational institutions, auditoria, broadcast and recording studios.
Frequently Asked Questions
What Rw rating do I need for a hotel room?
Hotel room entrance doors typically target Rw 36–42 dB depending on brand standard and corridor noise levels.
Do acoustic doors need a drop seal?
Yes — the threshold gap is the single biggest sound leak in a door. An automatic drop seal closes when the door shuts and is essential to reach published Rw values.
Can an acoustic door also be fire-rated?
Yes, combined acoustic + fire-rated doors are available. The full assembly must be specified together so that neither rating is compromised.
