Acoustic Door Selector
Tell us the space, the noise you need to block and how sensitive the neighbours are. We return the target STC rating, the right door build — solid-core, perimeter seals, an automatic drop seal, or a double-door sound-lock for STC 50+ — and an indicative ₹ per door. Indicative India 2026; confirm with an acoustic consultant for critical work.
Your space
Restful sleep — keep household and street noise out. A base STC for this space (32) is nudged up by the noise level (Conversation, television, office hum.) and neighbour sensitivity. STC = Sound Transmission Class — higher blocks more. Indicative; verify with an acoustic consultant on critical projects.
Target sound rating
STC 0

- Automatic drop seal (rising threshold seal)
Your target STC vs a hollow flush door (~24) and a basic solid-core (~36). Bands: red = basic, amber = sealed solid-core, green = acoustic + drop seal, cyan = double-door sound-lock.
