The Acoustic Camera was the first commercially viable system using beamforming to visually localize acoustic emissions. Brought to the market in 2001 as a pioneer technique, the Acoustic Camera has become over the years a metaphor for beamforming systems in general. The tool is now used in a variety of industries and has a growing customer base worldwide.

 | Acoustic AC Easy | | |
| Until today beamforming has been implemented in high end solutions in order to localize noise sources in a very precise and academically justified way. This development was necessary in order to build trust into the technology. The trust has indeed evolved and the Acoustic Camera has become a standard NVH measurement tool in numerous fields of application. However, due to the associated high price range of such a system the technology has not been accessible for many companies who see the need but lack the means. Gfai tech GmbH is changing this situation from now on. The development of the AC easy enables any SME to localize noise sources using this acoustic imaging technique. The Software NoiseImage4 is used for both product lines AC pro and AC easy. This does not block the hunger for extended analysis of its users independend of the acoustic camera product he is using. So even if you work with an AC easy system you'll find the same great software advantages as with the AC pro. The differences lay in the hardware. We do offer two main AC easy configurations; one based on a PC and the other on a National Instruments chassis as data acquisition. For different application we offer three specialized arrays; Sphere32-35 easy, Ring32-75 easy and Ring32-35 easy - Array.
The AC easy has the following key features:
• Affordable to anyone
• A beamforming beginner unit
• Live streaming
• Great ease of use
• Small, portable and compact
• Shows noise sources fast and reliable
Characteristics
- Software NoiseImage4 for PCs, Windows XP / 7
- Microphone arrays; Sphere32-35 easy, Ring32-75 easy and Ring32-35 easy
- standard Desktop PC with two microphone cards from National Instruments
(NI PCI 6250; 48kHz, 16bit resolution)
For Customers with more need of mobility we offer a more advanced configuration based on a National Instruments NI PXI-1033 chassis with two microphone cards (NI PXI 6250)connected to a notebook and an array. As well as for the PC based version you can chose from three differnt arrays; Sphere32 easy, Ring32 easy and Ring36.
