Hospitality Acoustics — Quiet Comfort, Better Reviews, Fewer Complaints
We design, model, and verify acoustic performance for hotels, resorts, and serviced apartments—reducing guest noise complaints, improving sleep quality, and protecting brand reputation.
Business outcomes for GMs & Owners
- Guest complaint rate ↓, review scores ↑ (comfort, sleep, privacy)
- Capex efficiency via model-driven optioneering before works
- Audit-ready deliverables aligned with brand and local codes
Typical issues we fix
- Corridor→room and room→room noise (doors, partitions, flanking)
- Footfall/impact from upper floors; gym/club structure-borne noise
- Façade noise ingress (traffic/nightlife), balcony leakage, glazing
- HVAC background noise masking sleep (FCUs, AHUs, duct breakout)
Design & verification targets (typical ranges)
| Parameter | Target (typ.) | Notes |
|---|---|---|
| Guest room background noise | ≤ 30 dB(A) (≈ NC-25/30) | Night; HVAC considered |
| Airborne isolation between rooms | DnT,w 50–55 (≈ STC/Rw 50–55) | Doors, flanking, penetrations |
| Impact sound (vertical) | L’nT,w ≤ 55 | Resilient layers, junctions |
| Façade sound insulation | D2m,nT,w 35–40 | Traffic/nightlife context |
| Reverberation (rooms) | RT60 ≈ 0.3–0.5 s | Perceived quietness |
Scope of work
- Diagnosis: complaint mapping, sample measurements, façade survey
- Modelling: prediction + options with costed impacts
- Design: partitions/doors, junctions, floating floors, mechanical noise control
- Implementation support: submittal review, site QA, contractor coordination
- Verification: ISO 16283 tests, RT, background noise, certification dossier
Instrumentation & methods
Class 1 SLMs with calibrators; omni sources + power amps; tapping machine; tests per ISO 16283-1/-2/-3 and ISO 3382-2.
Case snapshots
- Urban 5-star: door upgrade + corridor finishes reduced guest noise complaints by 42% within 60 days.
- Beach resort: balcony/façade retrofit achieved D2m,nT,w +6 dB, enabling premium room pricing.
