Environmental Noise Monitoring for Construction & Infrastructure in Asia

Norsonic noise monitoring systems are deployed on construction sites, metro tunnel projects, airport developments, and industrial facilities across Malaysia, Singapore, Philippines, Thailand, Vietnam, UAE, and Saudi Arabia for real-time authority-compliant monitoring, exceedance alerting, and automated reporting.

Construction Site Noise Monitoring

Continuous logging of LAeq, Lmax, Lmin, L10, L50, L90, L95 at 1-minute intervals
Real-time exceedance alerts via NorCloud — email and SMS on threshold breach
Audio event recording triggered by Lmax exceedances — evidence for authority and neighbours
Automated PDF and Excel reports formatted for authority submission (weekly or monthly)
Instruments: Nor145 for temporary deployments; Nor1545 for long-term or permanent installation

Types of Environmental Noise Projects

Urban construction: deep excavation, tunnelling, and demolition in dense residential areas
Infrastructure projects: metro rail lines, expressways, bridges, and airport expansion monitoring
Industrial fence-line: factory and power plant boundary noise compliance with permit limits
Airport perimeter: aircraft noise contour monitoring and community complaint management
Road and highway: long-term traffic noise assessment for barrier design and EIA reporting
Quarry and mining: blasting vibration and noise impact assessment at nearest sensitive receptor

NorCloud Data Management Platform

Web-based dashboard accessible from any device — no software installation required
Real-time LAeq time history and Lmax event list with audio playback
Configurable alert levels per time period (daytime, evening, night)
Multi-station network view — manage up to hundreds of monitoring points from one account
Export data in CSV, Excel, and standardized formats for third-party analysis

Case Studies

Metro construction, Kuala Lumpur — 24/7 tunnelling monitoring with 6× Nor1545 stations; zero authority exceedance notices across weeks of continuous operation; real-time NorCloud alert notifications to contractor and authority
Airport access road, Manila — baseline noise survey and EIA reporting using Nor145 with GPS and NorCloud
Hospital zone, Bangkok — construction noise managed below WHO healthcare facility limits throughout project duration
