Building Acoustics with Nor150 (2ch)

Dual-channel building acoustics solution for ISO 16283 field testing.

Overview

The Nor150 dual-channel building acoustics solution delivers the most efficient and comprehensive approach to ISO 16283 field sound insulation testing. By measuring simultaneously in both the source and receiving rooms, the dual-channel Nor150 eliminates synchronization challenges and dramatically reduces on-site testing time compared to single-channel sequential methods. This efficiency advantage…

Key Features

  • Simultaneous dual-channel source and receiver room measurements
  • ISO 16283-1 airborne sound insulation testing with automated sequences
  • ISO 16283-2 impact sound insulation testing with tapping machine and impact ball
  • ISO 16283-3 facade sound insulation assessment capability
  • Real-time DnT,w and L'nT,w calculation with spectrum adaptation terms
  • Automated measurement sequences for consistent, standardized testing
  • Low-frequency procedure per ISO 16283-1 Annex A for small rooms
  • Compatible with Nor277 tapping machine, Nor279 impact ball, and Nor283 dodecahedron

Frequently Asked Questions

  • Why use dual-channel for building acoustics?
    Dual-channel operation enables simultaneous source and receiver room measurements, eliminating synchronization issues, reducing measurement time by up to 50%, and improving data consistency. This is especially valuable on large projects where hundreds of partitions must be tested within tight construction schedules.
  • What sound sources are required?
    Airborne sound insulation testing requires the Nor283 dodecahedron loudspeaker with Nor280 or Nor282 power amplifier. Impact sound insulation testing requires the Nor277 tapping machine for standard impacts and optionally the Nor279 impact ball for low-frequency heavy impact assessment per ISO 16283-2 Annex B.
  • Does the system calculate single-number ratings automatically?
    Yes, the Nor150 calculates standardized level differences (DnT,w) and normalized impact sound pressure levels (L'nT,w) with spectrum adaptation terms (C, Ctr) in real time, providing immediate pass/fail assessment against building code requirements on site.
