2. Sorama CAM1K :
The CAM1K is the top-of-the-line product in the Sorama assortment of sound cameras. An ideal tool for each company with focus on optimized noise performance of their products. The visual insights make it easy to interpret and explain causes of noise and vibration. We enable fast and efficient ways to improve sound design.
The benefits of the CAM1K are in its size. Far-field beam forming already starts at 50 Hz and the larger microphone array gives a better resolution of sound sources. Near-field acoustic holography
is up to 30 times faster than other cameras, including our own CAM64. Sorama CAM1K is the ultimate tool for NVH engineers working on OEM products.
Main specifications:
- Far Field beamforming:50Hz and up with optimal conditions at 300Hz – 15kHz
