The Norsonic Nor848A sets a new standard for acoustical cameras. The large number of microphones eliminates the problems of ghost-spots, compared to traditional acoustical cameras where the relatively low number of microphones increases the side lobe effect, resulting in the so called ghost-spot effect. You measure a non-existing source. The Nor848A software is extremely intuitive and easy to use. Just after a few minutes of training, the user is able to operate the system and do real measurements. Three camera frontends are available.
A 0.4m array with 128 microphones, a 1 meter array holding 256 microphones and a 1.6 meter array with 384 microphones! The system enables the user to perform noise analysis with a clear view of the spatial distribution of the sound in real time! The system is easy to set up in the field. Just power the self-contained unit from mains or battery and connect the LAN cable to the computer. The system is ready to measure in just a few minutes after entering the site.
Robust camera front-end based on a circular carbon fiber disc, three sizes available:
- 128 microphones 0.4 meter array
- 256 microphones 1 meter array, only 11 kg weight
- 384 microphones 1.6 meter array for lower frequency analysis
No interface box between array and laptop, direct connection with LAN cable
Listen to and analyze real time audio from virtual microphone position
Virtual microphone enables you to listen to the sound contribution from any source real time, filtered with your selected frequency range
Microphones on a disc prevent sound and echo from behind
Low self-noise and large measurement range
RPM option for analyzing rotating machines.
High-performance optical video camera are included in the camera front-end unit
The distribution of the high number of microphones ensures high resolving power and reduces the problems due to side lobe effects compared to most other acoustic cameras
Digital microphones ensure large dynamic range and high stability
Simple connection to the included MacBook Pro computer through a single LAN-cable.
All parts are integrated in the camera frontend – no need for a signal processing interface box
Operated on mains or DC input
Records the signal from every microphone
