KLIPPEL Demonstration of In-Situ Room Compensation (ISC)

Most standard measurements are performed at a single point (e.g. 1m On-Axis). The In-Situ Room Compensation (ISC) module copes with an imperfect acoustical environment by calculating a complex filter that compensates for room effects. Using this technique, simulated free field data can be acquired according to the IEC standard 60268-21.

This video gives an overview of the module, a practical demonstration of In-Situ measurement, handling tips and a compensation method comparison. It's a great way to learn about our anechoic room solution for measuring any loudspeaker in any room under standard conditions.
