The CS18 FF was developed as a compact system for calibration in the acoustic free field. The anechoic calibration chamber can be set up in a normal quiet room of a building without any structural modifications. Therefore, it also offers smaller calibration laboratories a cost-effective way to offer free-field calibrations in an interesting frequency range.
A pressure comparison calibration for pressure microphones is possible with the CS18 SPL. The possibilities of both systems can be combined in the CS18 FF/SPL.
All systems can also be upgraded for electrical calibration of signal conditioners, such as microphone amplifiers (measurement microphone or IEPE types).
