The Nor848B acoustic camera can realize real-time color mapping of sound location generated from numerous MEMS microphones and high-speed data processing software. The all-in one solution consisted from main unit with microphones/camera and computer allows very easy set up so that you can instantly start measurement on site without external power supply. Surprising accuracy, dynamic range, and resolution gives  important clue to those who wants to identify the cause of sound and noise source.

Software

The software is designed to be extremely user-friendly while it can analysis in deep.

• Adjustable dynamic range for more intuitive sound location
• Virtual microphone to listen to the sound from selected sound location
• Recording video and acoustic data for post-processing
• Acoustic eraser for masking the close located sound source
• Order analysis to get the coherence of noise data and RPM

Product configurations

3 combination of acoustic camera are available according to the target measurement frequency desired resolution:

Hextile – lightweight and portable

With a single Hextile, it is very small for easy-to-carry setup. The Hextile is a USB based acoustic camera, with a single USB cable for both power and data transfer – no extra battery cable needed. The array is made from robust and lightweight aluminium, has 128 MEMS microphones, and is less than 3 kg in weight while having a maximum diameter of 46 cm. The low frequency limit for the Hextile is 410 Hz.

Multitile – Great resolution

For users that require better resolution both in lower frequencies and overall, three single Hextiles can be combined to a larger Multitile system, consisting of 384 microphones with a maximum diameter of 96 cm. The low frequency limit for the Multitile is 220 Hz.

Multitile (LF mode) – Low frequency measurements

For special low frequency applications below 1 kHz, it is also possible to utilise the Multitile in the low frequency configuration as the Multitile (LF mode). By placing the individual Hextiles further away, the maximum diameter of the complete array system is increased to 1.46 m, making it ideal for low frequency measurements. The Multitile (LF mode) is for low frequency measurements below 1 kHz, with a lowest frequency limit of 120 Hz.
