Acoustic Camera

Product Code: NOR-848A

New 848a Acoustic camera fully updated. Seeing Sound!

The Norsonic Nor848A sets a new standard for acoustic cameras. The large number of microphones eliminates the problems of ghost-spots, compared to traditional acoustic cameras where the relatively low number of microphones, results in the so called ghost-spot effect. Pinpoint your sound and any acoustic leaks quickly and easily in real time!

EASY TO USE

The Nor848 is quick and easy to set up before the noise analysis is performed with it's 5 min plug and play feature. This advanced acoustic camera allows the user to pin point the sound source and even listen to different areas of the recorded environment!

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.

From the biggest car manufactures to government bodies, companies all over the globe are seeing the benefit of the acoustic camera.
