The combination of flexibility and guided measurement sequences is truly impressive. The matrix saves us a lot of time in planning and executing our measurement campaigns.

What if complex NVH measurements could be started with just a few clicks – in compliance with standards, reproducible, and immediately evaluable?

In test benches, development laboratories, and production halls, every test run counts. The PAK matrix automates standardized measurements such as sound power, reverberation time, and sound insulation—precisely, quickly, and scalably. This not only saves time, but also takes your acoustic processes to a new level.

Starting point & relevance

In industries such as the automotive and aviation industries, mechanical and plant engineering, or building acoustics and noise control technology, standard-compliant NVH measurements are essential for product development, quality assurance, and certification. The wide variety of standards (e.g., ISO 3744, ISO 10534-2, ISO 3382-2) places high demands on process efficiency, documentation, and reproducibility.

Deeper insights and faster decisions through automated measurement data classification, real-time statistics, and process-driven workflows help improve test efficiency and ensure compliance:

Determination of reverberation time in ordinary rooms
- ISO3382_2
- ISO3382_2_SS
Determination of sound absorption coefficient and impedance in impedance tubes
- ISO10534_2
Determination of sound insulation (transmission loss) and sound insulation index
- SAE_2003-01-1653
- ASTM_E2611
Determination of sound power and sound energy levels of noise sources
- ISO3743_1
- ISO3743_2
- ISO3744
- ISO3745
- ISO6395_ISO6396 (Earth-moving machinery)
Determination of noise and vibration for hand-held electric tools
- ISO15744_IEC62841_1
- ISO28927
Start-up and shut-down measurements
Track comparisons

Challenge

Manual measurement processes involve risks: operating errors, inconsistent results, time-consuming evaluations, and lack of standard compliance. This leads to delays, unnecessary costs, and uncertainty in decision-making, especially in the case of recurring tests or complex measurement series.

Solution

The PAK matrix standardizes and automates NVH measurement processes – from preparation to analysis. It guides users through predefined workflows, complies with common NVH standards, and enables seamless integration into existing test environments. Real-time analyses and automated reports make results immediately usable.

Process

1. Preparation

Selection of the measurement standard (e.g., ISO 3745, ASTM E2611)
Configuration of the measurement environment and channels

2. Implementation

Sequence-oriented test execution in accordance with standard requirements
Automatic data collection & validation

3. Analysis

Real-time evaluation (e.g., sound power level, impedance curves, reverberation time)
Statistical key figures: mean value, min/max, deviations

4. Derivation

Optimization suggestions based on measurement results
Generation of standard-compliant compliance reports

Results

Reduction in development time
Improved acoustic performance
Faster troubleshooting with significant cost savings
High process reliability through standardized workflows
Error prevention through user guidance

Customer benefit

✅ User-friendly – even for non-NVH experts thanks to guided processes
