Nor850 Room Acoustics (ISO 3382)

The Nor850 Room Acoustics module is a specialized add-on for the Nor850 Reporting Software platform, providing comprehensive analysis and reporting capabilities for room acoustics measurements performed according to ISO 3382. The module calculates a full set of room acoustic parameters from impulse response and interrupted noise measurements captured by the Nor145 or Nor150 analyser. Calculated parameters include reverberation time (T20, T30, EDT), clarity indices (C50 for speech, C80 for music), definition (D50), centre time (Ts), lateral energy fraction, and Speech Transmission Index (STI) per IEC 60268-16. These parameters are computed across standard frequency bands with spatial averaging across multiple source-receiver positions. Decay curve analysis with Schroeder integration is provided for detailed investigation of room response characteristics. The module supports multi-position measurement campaigns with statistical averaging and spatial distribution analysis, enabling assessment of acoustic uniformity across large spaces. Professional report templates generate standards-compliant documentation with frequency-dependent parameter charts, comparison against target values, and spatial distribution maps suitable for design verification, commissioning certification, and acoustic consultancy deliverables. For acoustics consultants, architects, and facility operators across the GCC, this module is essential for verifying room acoustics performance in concert halls, mosques, auditoriums, classrooms, open-plan offices, and hospitality venues. The growing emphasis on acoustic quality in Vision 2030 developments makes room acoustics assessment an increasingly important component of building commissioning programs.
