With sound localization, we were able to easily identify the components that were emitting the disruptive frequencies – and eliminate the problems.

Initial situation & relevance

In the acoustic development of modern vehicles, machines, and technical systems, it is not only important to measure noise, but also to locate it precisely. Without exact sound source localization, many acoustic causes remain unidentified – with direct consequences for development time, product quality, and customer satisfaction.

Challenge

How can multiple sound sources be identified and spatially assigned simultaneously?
How can acoustic analysis be linked to operating data such as speed or temperature?
How can robust troubleshooting be achieved that can be integrated directly into development cycles?

Results

Reliable localization of acoustic weak points
Shortening of troubleshooting cycles
Transparency regarding acoustic behavior
Reduction of rework and development costs

Customer

✅ Fast and cost-efficient sound source localization
✅ Linkage to system variables for deeper analysis
✅ Intuitive evaluation and easy repeatability
✅ Improved product quality and customer satisfaction

⭐️ Key Features

Acoustic localization with microphone array – even for moving objects
Real-time visualization and frequency analysis
Integration with PAK live and PAK classic
Link to physical influencing factors
Suitable for wind tunnels, exhaust gases, passing vehicles, overflights, wind power, engine compartments

✅Conclusion

PAK sound localization brings the invisible to light: noises become measurable, localizable, and can be optimized in a targeted manner. This saves time and resources and increases competitiveness in every phase of acoustic development.
