Building Acoustics with Nor145 (1ch)

The Nor145 single-channel building acoustics solution provides a fully ISO 16283-compliant approach to field sound insulation testing at a significantly lower investment than dual-channel systems. By performing sequential measurements in the source and receiving rooms, the Nor145 delivers the same standardized results as dual-channel methods while requiring only one instrument and one microphone channel. This makes it an excellent choice for smaller consultancies, independent acoustic testers, and budget-conscious projects across the GCC construction market. The Nor145 supports all ISO 16283 test types including airborne sound insulation (Part 1), impact sound insulation (Part 2), and facade sound insulation (Part 3). The operator measures the source room level first, then moves the instrument to the receiving room for the second measurement. Timer functions and stable sound sources ensure adequate overlap or sequencing for reliable level difference calculations. The Nor850 Building Acoustics module then combines the sequential measurement data to calculate standardized ratings including DnT,w and L'nT,w with spectrum adaptation terms. For building acoustics professionals entering the GCC market or working on smaller-scale residential and commercial projects, the Nor145 provides an affordable pathway to professional acoustic testing capability. Its Class 1 accuracy, 4.3-inch touchscreen, and integrated 4G/WLAN connectivity deliver the same measurement quality as premium instruments, while the single-channel approach keeps the initial investment manageable. When project volumes grow or efficiency requirements increase, the upgrade path to the dual-channel Nor150 ensures continuity of measurement data and reporting workflows.
