Frequently Asked Questions: Hotels & Hospitality

What STC rating is required between hotel guest rooms?▾
Luxury hotels target STC 55–60 between guest rooms, while mid-range hotels require a minimum STC 50. IBC 2021 §1207 mandates STC 50 for residential occupancies. The partition must address flanking paths through the floor slab, ceiling plenum, and window mullions, which often reduce the apparent STC by 5–10 points below laboratory ratings.
How do you reduce noise in hotel corridors?▾
Hotel corridor noise control requires acoustic door seals (STC 35+ door assemblies), absorptive corridor ceiling treatments, and carpet or resilient flooring to reduce impact noise. Elevator lobbies should be isolated from guest room corridors with vestibule doors. Background noise from ice machines and vending equipment must be attenuated to NR 30 at the nearest guest room.
What acoustic treatment is needed for hotel conference rooms?▾
Hotel conference rooms require RT60 ≤0.6 seconds for clear speech intelligibility during presentations and video calls. This typically involves absorptive ceiling tiles, fabric-wrapped wall panels on at least two wall surfaces, and carpet flooring. Operable partition walls between divisible conference spaces should achieve STC 52+ to prevent cross-talk during simultaneous events.
