Nor848B Acoustic Camera

The Norsonic Nor848B acoustic camera is a modular beamforming array system built in a solid aluminum housing that enables engineers to visualize, localize, and quantify noise sources in real time. Based on the innovative Hextile modular array technology, the Nor848B can be configured from a single portable tile to a full 384-microphone Multitile array, giving acoustics professionals the flexibility to address everything from quick field inspections to detailed laboratory NVH investigations. The Nor848B produces real-time color-mapped sound source images overlaid on the live feed from its high-performance optical video camera at 2592 × 1944 resolution, making noise sources immediately visible to engineers, maintenance teams, and facility managers. Advanced beamforming algorithms including delay-and-sum and MVDR deliver superior spatial resolution across the 30 Hz to 24 kHz frequency range. A software-based virtual microphone allows the user to listen to sound arriving from any selected direction while suppressing all other sources — available both during real-time analysis on site and during post-processing of recorded data, enabling detailed audio examination of individual sources after the measurement is complete. For rotating machinery applications, the Nor848B supports RPM and order tracking, enabling engineers to identify speed-dependent noise sources and track their behaviour across the operating range. Raw data recording stores the full microphone array signal for post-processing, giving analysts the flexibility to apply different algorithms, frequency weightings, or virtual microphone positions after returning from site. For industrial facilities across Saudi Arabia, the UAE, and the wider GCC region, the Nor848B is an indispensable tool for noise control engineering. Oil and gas processing plants, power generation facilities, petrochemical refineries, and desalination plants can use the acoustic camera to rapidly identify and rank noise sources for targeted mitigation. This supports compliance with occupational noise exposure limits and community noise regulations enforced by Saudi PME and UAE environmental agencies under Vision 2030 sustainability and quality-of-life objectives. The portable Hextile configuration weighing just 2 kg makes the Nor848B ideal for on-site troubleshooting of HVAC systems, transformer stations, and production line equipment. The larger Multitile configuration extends low-frequency capability down to 50 Hz, enabling detailed noise mapping of large industrial machinery, wind turbines, and building facades. With comprehensive post-processing software and export capabilities for client reporting, the Nor848B provides a complete workflow from measurement to deliverable.
