Martijn Fokker rejoins our design department
This is a man who loves the impossible. After seven years, we welcome Martijn Fokker back to the Comtest family. “I have been working at Comtest for 16 years and thought it was time for something different, but there’s something about these chamber projects that kept me coming back,” says Martijn.

Will 2026 finally see the adoption of reverberation testing in the automotive industry? In a series of five posts, our specialists share trends and developments for 2026. This week, Dimitrios Barakos, R&D Engineer at Comtest, explains the delays in 2025.
Dimitrios: “Although the ISO standard for full-vehicle testing was completed some time ago, the necessary ISO-11542-11 update for automotive components has been pushed back. There is a bright side: in 2027, Hyundai Motor Group will likely make the updated ISO standards mandatory for testing their vehicles and motor components. However, that was expected in 2025 and has been delayed, as you know. For 2026, these delays will leave the automotive industry with only half the incentive to embrace reverberation testing.”
When do you see acceptance for reverberation testing in the automotive industry?
Dimitrios Barakos: “The point is that the new norms for full-vehicle testing are not mandatory, and switching from anechoic to reverberation testing is not very popular. Some companies are open to it, and big labs and test houses see the potential of reverberation testing, but for many, it remains an unfamiliar method. At the Comtest R&D department, we continue developing improvements to our reverberation chambers. We have been optimising our current range of stirrers, and we are also working on a new type of stirrer. We keep improving the product to stay ahead of the game.”
