Environmental Measurements with Nor150

Advanced environmental noise monitoring with dual-channel Nor150.

Overview

The Nor150 environmental noise monitoring solution extends the capabilities of standard environmental assessment with dual-channel measurement, vibration monitoring, and advanced real-time FFT analysis. While the Nor145 covers most standard environmental noise applications, the Nor150 addresses complex scenarios requiring simultaneous multi-point measurements, combined noise and vibration assessme…

Key Features

  • Dual-channel simultaneous measurement for indoor/outdoor noise assessment
  • ISO 1996 compliant environmental noise monitoring and assessment
  • Vibration measurement per ISO 8041 for combined noise/vibration studies
  • Real-time FFT analysis with up to 6400 lines for tonal component identification
  • Synchronized dual-point statistical analysis (LAeq, Lmax, L10, L50, L90)
  • Built-in 4G LTE and WLAN with NorCloud remote monitoring integration
  • Audio recording for source identification during noise events
  • GPS/GNSS location tagging for audit-ready geo-referenced documentation

Applications

  • Complex environmental noise assessments requiring simultaneous multi-point data
  • Simultaneous indoor/outdoor noise measurement for noise intrusion studies
  • Combined noise and vibration impact assessment for construction projects
  • Tonal noise component analysis for industrial source characterization
  • Blast and construction vibration monitoring per ISO 4866 and BS 7385
  • Transportation corridor noise and vibration assessment

Technical Specifications

  • Analyzer: Nor150 (dual channel)
  • Standards: IEC 61672-1 Class 1
  • Channels: 2 simultaneous
  • Analysis: Real-time FFT, statistics

Frequently Asked Questions

  • When should I choose the Nor150 over the Nor145 for environmental work?
    Choose the Nor150 when you need dual-channel capability for simultaneous measurements at two positions, vibration measurement for combined noise/vibration assessments, real-time FFT analysis for tonal noise characterization, or 1/12 octave band resolution for detailed frequency investigations.
  • Can both channels measure different locations simultaneously?
    Yes, with appropriate cabling the two channels can monitor separate positions simultaneously. For example, one channel can measure outdoor ambient noise while the second measures indoor noise at a receptor position, providing synchronized data for noise intrusion analysis.
  • Does the Nor150 support vibration monitoring for construction projects?
    Yes, the Nor150 includes ISO 8041 vibration measurement capability. With an appropriate accelerometer, it can monitor construction vibration, blast vibration, and traffic-induced vibration simultaneously with noise measurements, providing a comprehensive environmental impact assessment.

Application Guide

The Environmental Measurements with Nor150 belongs to the Norsonic Noise Monitoring range. See the Noise Monitoring application guide for system configuration, compatible accessories, and applicable measurement standards.
