We knew something was causing the interference, but we didn't know what. With sound power measurement, we were able to pinpoint the problem and fix it.
Starting point and relevance
In development, production, and testing processes, the precise evaluation of sound emissions is becoming increasingly important. Compliance with legal standards, product quality requirements, and growing customer demands for acoustic comfort make the determination of sound power an essential parameter in the NVH environment.

Challenge
Many test setups are characterized by complex sound source distributions, disturbing background noise, or unfavorable room acoustics. Under these conditions, a standard-compliant, repeatable, yet flexible evaluation of sound power is technically challenging—especially when different standards (e.g., ISO 374x, DIN 45635) must be taken into account.
⭐️ Key Features
- Support for all relevant standard procedures
- Application in free fields and reverberation rooms
- Real-time sound power calculation
- Integration into existing PAK system environment
- Flexible frequency resolution (including 1/3 octave)
- Consideration of background noise
✅ Conclusion
The Sound Power Module combines measurement accuracy, standard compliance, and process efficiency for meaningful acoustic evaluations in development, quality assurance, and research.
