Residential Acoustics — Peaceful Living, Real Privacy
Independent design and verification for condominiums and apartments—better sleep, fewer neighbour complaints, higher asset value.
Outcomes for developers & juristic persons
- Complaint rate ↓, buyer satisfaction ↑
- Predictable handover—clear targets & verification
- Retrofit options where construction is complete
Typical issues we fix
- Party-wall noise (voices/TV), door/soffit leakage, flanking
- Footfall/impact from upper units; stairwell and lift noise
- Façade/traffic noise; balcony and window leakage
- Mechanical noise (FCUs, compressors, pumps)
Design & verification targets (typical ranges)
| Parameter | Target (typ.) | Notes |
|---|---|---|
| Background noise | Bedrooms ≤ 30–35 dB(A) | Night; HVAC included |
| Airborne isolation (inter-unit) | DnT,w 50–55 (≈ STC/Rw 50–55) | Detailing & flanking critical |
| Impact noise (vertical) | L’nT,w ≤ 58 | Floor build-ups & resilient layers |
| Façade sound insulation | D2m,nT,w 35–40 | Site exposure dependent |
| Reverberation (living spaces) | RT60 ≈ 0.4–0.6 s | Comfort & speech clarity |
Scope of work
- Diagnosis: complaint logs, sample tests, leakage mapping
- Modelling & options: partitions, floors, façades
- Detail design: drawings, junctions, BoQ
- Implementation support: RFIs, site QA
- Verification: ISO 16283, ISO 3382-2, report pack
FAQs
Can we retrofit with minimal disruption?
Yes—targeted door/partition upgrades, resilient underlays, and balcony/façade sealing are staged by stack or floor.
What data do you need?
Plans/sections, wall/floor build-ups, MEP schedules, complaint logs, unit matrix.
