The Nor145 room acoustics measurement solution offers a cost-effective approach to ISO 3382-compliant room acoustic assessment using Norsonic's single-channel Class 1 sound level meter. While the dual-channel Nor150 is the premium choice for comprehensive room acoustics surveys, the Nor145 provides all the essential capabilities needed for reverberation time measurement and basic room acoustic parameter evaluation at a significantly lower investment, making it an ideal entry point for consultants, facility managers, and educational institutions across the GCC. The Nor145 captures impulse responses using interrupted noise or impulsive source methods and calculates reverberation time parameters T20, T30, and EDT across 1/1 and 1/3 octave frequency bands. The large 4.3-inch touchscreen displays decay curves in real time, allowing operators to verify measurement quality on site before moving to the next position. Multi-position measurements can be performed sequentially and averaged in Nor850 reporting software to produce results compliant with ISO 3382-2 for ordinary rooms including classrooms, offices, and worship spaces. For GCC educational authorities assessing classroom acoustics, facility managers verifying acoustic treatment in auditoriums, and consultants performing routine reverberation time checks on commercial spaces, the Nor145 provides professional-grade accuracy in a portable, user-friendly package. The built-in 4G LTE connectivity enables remote support during measurements, while GPS tagging documents the exact measurement location for audit-ready reporting. When paired with the Nor283 dodecahedron loudspeaker or Nor286 ORIGAMI impulse source, the Nor145 forms a complete, budget-friendly room acoustics measurement system suitable for most standard applications.
