Nor848B Acoustic Camera

Nor848B modular acoustic camera with Hextile array technology for real-time sound source localization and visualization in industrial, automotive, and building applications.

Overview

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 flexibilit…

Frequently Asked Questions

  • What is the difference between Hextile and Multitile configurations?
    Hextile offers a lightweight, portable single-array solution weighing just 2 kg, ideal for field troubleshooting and on-site inspections. Multitile combines multiple arrays for higher spatial resolution and extended low-frequency capability down to 50 Hz, making it better suited for detailed laboratory NVH analysis and large industrial equipment.
  • Can the acoustic camera measure low frequencies?
    Yes. The Multitile LF mode extends the measurement range down to 50 Hz, enabling identification of low-frequency noise sources from large industrial machinery, transformers, and HVAC systems commonly found in GCC industrial facilities.
  • Is real-time visualization available?
    Yes. The Nor848B provides real-time color-mapped sound source visualization overlaid on a live video feed at up to 50 frames per second. This enables immediate identification of noise sources during on-site walkthroughs and troubleshooting sessions.
