5. Noise Cannot Be Hidden!
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,
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,
Records the signal from every microphone.

7. Noise source with complicated geometry can be detected really fast with acoustic camera.
Fast analyze of exact noise type can be done with intensity method as systems have more than one noise source.
Issue can be fixed on it’s source.
Easy to present solutions with saving time and cost.
