NVH testing requires the combined evaluation of noise, vibration and harshness to understand structural and acoustic performance. m+p international provides a powerful NVH platform with high-resolution acceleration and sound pressure measurement, dual-Y visualization, octave band analysis, order analysis, sound power and sound intensity evaluation. With synchronized acquisition, true octave filtering, noise excitation via Analyzer signal generation and microphone recording in VibControl, engineers can identify NVH sources, verify NVH requirements and optimize noise and vibration behavior across automotive, aerospace and industrial applications

NVH testing requires simultaneous acquisition of structure-borne vibration and airborne sound to interpret noise and vibration behavior accurately.

The Analyzer provides synchronized acceleration and sound pressure measurement with dual-Y visualization, allowing engineers to correlate noise and vibration levels precisely for complete NVH analysis.

NVH engineering demands accurate octave band analysis and rotational order tracking to identify noise and vibration sources under dynamic conditions.

The Analyzer offers true digital octave filters and advanced order analysis, enabling detailed noise vibration harshness analysis and compliance with NVH standards across operating speeds.

Sound quality analysis and sound power determination require reliable acoustic evaluation tools beyond simple spectral displays.

Engineers can use sound power, sound intensity and sound level analysis within the Analyzer to assess airborne noise, evaluate NVH specifications and characterize acoustic emission precisely.

Squeak-and-Rattle phenomena require combined microphone and accelerometer measurements during vibration qualification or transport simulation.

VibControl enables parallel recording of microphone and vibration channels, supporting Squeak-and-Rattle evaluations and providing engineers with synchronized data for diagnosing NVH issues under test conditions.

NVH engineering often requires derived metrics such as velocity, displacement, sound velocity or filtered RMS values that are not directly available in raw signals.

The Analyzer includes powerful calculator functions for integration, differentiation and physical conversions, allowing engineers to create new NVH signals and perform detailed FFT spectrum analysis.

Some NVH testing methods require controlled acoustic excitation, such as white noise or pink noise, to evaluate system response or structural-acoustic coupling.

The Analyzer’s signal generator provides white, pink and brown noise, sweeps and arbitrary signals, enabling controlled acoustic excitation for NVH testing, sound quality analysis and structural-acoustic investigations.

NVH analysis workflows depend on exporting data into MATLAB, FEA tools or customer-specific NVH software, requiring clean, compatible file formats.

The Analyzer and VibControl offer export to ASCII, CSV, MATLAB (.mat), binary and UNV, ensuring seamless integration with NVH software, simulation verification and noise vibration harshness analysis.

NVH investigations often involve large datasets, multi-sensor setups and iterative test cycles, increasing workload for development teams.

m+p provides guided NVH workflows, synchronized multi-domain acquisition and advanced frequency-domain visualization, enabling teams to work efficiently and optimize noise and vibration behavior throughout product development.
