Frequently Asked Questions

  • What makes the Nor150 different from the Nor145?
    The Nor150 adds dual-channel capability, sound intensity measurement, vibration analysis per ISO 8041, and real-time FFT with up to 6400 lines resolution. It is designed for research-grade building acoustics, sound intensity, and vibration applications beyond basic noise measurement.
  • Can the Nor150 perform sound intensity measurements?
    Yes. When paired with the Nor1290 sound intensity probe kit, the Nor150 enables ISO 9614-compliant sound power determination. The dual-channel architecture provides the phase-matched measurement capability required for accurate intensity calculations.
  • Is the Nor150 suitable for building acoustics testing?
    Absolutely. The Nor150 supports airborne sound insulation testing per ISO 16283-1, impact sound insulation per ISO 16283-2, and reverberation time measurement per ISO 3382. Its dual-channel operation enables simultaneous source and receive room measurements for efficient on-site testing.
