Grade-A Office: Open-Plan Speech Privacy Fix

Bangkok

An A-grade office reported high speech intelligibility across work zones. Using Class 1 logging, octave analysis, and targeted ceiling/absorption tuning, we validated design changes and closed out with objective privacy metrics aligned to global benchmarks.

-6 to -8 dB(A) LAeq in focus zones

STI reduced from 0.55 to 0.40

Metro Extension: Night-Time Construction Compliance

Kuala Lumpur

Contractor required night-work monitoring near residences. We deployed remote Class 1 meters with alerts and produced defensible reports for authorities, enabling schedule adherence without violations.

0 compliance breaches across 9 weeks

Real-time alerts < 60s latency

Reporting cycle reduced by 50%

University Dorms: Wall/Floor Upgrades Validation

Singapore

Post-retrofit, the client needed proof of acoustic uplift. Source/receiver room tests with calibrated sources confirmed targets and supported phased investment decisions.

DnT,w improvement +7 dB

Impact noise Ln,w improved -9 dB

Rework avoided on 18 rooms

Hospitals: Nurse Station Quieting

Ho Chi Minh City

Elevated background noise impacted staff fatigue. We profiled spectral contributors and optimized finishes and masking strategy.

LAeq -5 dB(A) daytime

22% reduction in peak exceedances

Industrial Plant: Tonal Noise Mitigation

Rayong

Community complaints traced to a tonal fan component. Narrowband analysis isolated the frequency; targeted treatment resolved the issue with minimal CapEx.

Tonal prominence removed (delta Lta < criterion)

Complaints dropped to zero in 30 days

Avoided enclosure cost > US$75k
