The Nor150 room acoustics measurement solution provides a comprehensive, ISO 3382-compliant system for evaluating the acoustic performance of enclosed spaces. From concert halls and conference centres to classrooms, mosques, and auditoriums, the Nor150 captures impulse responses and calculates the full suite of room acoustic parameters including reverberation time (T20, T30, EDT), clarity indices (C50, C80), definition (D50), and Speech Transmission Index (STI) per IEC 60268-16. The dual-channel architecture enables simultaneous source and receiver measurements for maximum efficiency during large-scale surveys. The Nor150 supports multiple excitation methods for impulse response capture. Engineers can use the Nor283 dodecahedron loudspeaker with the built-in signal generator for standardized interrupted noise or MLS/sweep excitation, or employ impulsive sources such as the Nor286 ORIGAMI for rapid spot checks. Multi-position averaging is handled automatically, allowing operators to efficiently survey multiple source-receiver combinations as required by ISO 3382-1 for performance spaces and ISO 3382-2 for ordinary rooms. Real-time display of decay curves and parameter results on the 4.3-inch touchscreen enables immediate quality assessment in the field. For architects, acoustic consultants, and facility managers across the GCC, room acoustics measurements are essential for verifying design intent in newly constructed performance venues, ensuring speech intelligibility in educational facilities, and assessing worship spaces where clarity and reverberation balance are critical. The Nor850 reporting software with the Room Acoustics module generates professional ISO 3382 test reports with decay curves, parameter tables, and spatial distribution charts. This complete measurement-to-report workflow makes the Nor150 the preferred choice for room acoustics professionals working on Vision 2030 cultural, educational, and hospitality projects throughout Saudi Arabia and the wider Middle East.
