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.
