The Signal Path: 10 essential softwares for noise & vibration engineers

Generated with the help of AI, fact checked by Industry Experts

NVH (Noise, Vibration, and Harshness) engineering sits at the intersection of acoustics, structural dynamics, signal processing, and human perception. From powertrain excitation and wind noise to interior sound quality and modal behavior, NVH engineers rely on a specialized software toolkit to diagnose issues and guide design decisions.

Below are exactly 10 essential software tools widely used across automotive, aerospace, and industrial NVH engineering.


1. Siemens Simcenter Testlab (formerly LMS Test.Lab)

Primary focus: NVH testing, modal analysis, and system dynamics

Simcenter Testlab is one of the most widely used platforms for professional NVH measurement and analysis. It supports multi-channel data acquisition, experimental modal analysis, operational deflection shapes, order tracking, and sound quality evaluation. It is a cornerstone tool for powertrain NVH, body-in-white testing, and vehicle-level diagnostics.

Industry use:
Vehicle NVH testing, modal testing, powertrain and driveline analysis


2. HEAD acoustics Software Suite (HEADlab, HEADcompanion, ArtemiS)

Primary focus: Sound quality and psychoacoustics

HEAD acoustics provides a comprehensive ecosystem of NVH tools.

  • HEADlab is used for data acquisition and measurement
  • HEADcompanion enables playback, auralization, and subjective evaluation
  • ArtemiS handles advanced post-processing and psychoacoustic metrics

Together, these tools are essential for linking objective measurements with human perception—especially in interior noise and sound quality work.

Industry use:
Interior sound quality, wind noise, subjective-objective correlation


3. MATLAB

MATLAB is the backbone of custom NVH analysis. Engineers use it for FFT analysis, filtering, order analysis, modal parameter extraction, scripting of test workflows, and advanced data visualization. Its flexibility makes it ideal for developing proprietary NVH metrics and post-processing pipelines.

Industry use:
Custom NVH analysis, algorithm development, test automation


4. Simcenter 3D (NVH / Acoustics / Motion)

Primary focus: CAE-based NVH simulation

Simcenter 3D is widely used for predicting NVH performance before hardware exists. It supports structural dynamics, acoustic FEM/BEM, vibroacoustic coupling, and transfer path analysis. This tool is critical for early-stage design of powertrains, body structures, and interior acoustics.

Industry use:
Virtual NVH, structure-borne noise prediction, design optimization


5. Abaqus

Primary focus: Structural dynamics and vibration

Abaqus is commonly used for high-fidelity structural modeling and vibration analysis. NVH engineers rely on it to understand resonance behavior, damping treatments, and structural responses that lead to radiated noise or harshness.

Industry use:
Structural vibration analysis, durability-NVH interaction, modal behavior


6. COMSOL Multiphysics

Primary focus: Vibroacoustic and multiphysics simulation

COMSOL excels at coupled simulations involving structures, acoustics, fluids, and electromagnetics. It is particularly useful for wind noise studies, cavity-structure coupling, and complex boundary conditions where traditional single-domain solvers fall short.

Industry use:
Wind noise modeling, vibroacoustics, acoustic-structure interaction


7. Brüel & Kjær PULSE / BK Connect

Primary focus: Measurement and NVH analysis

Brüel & Kjær’s software platforms are deeply integrated with their hardware systems. They support sound and vibration measurement, order tracking, modal testing, and transfer path analysis, making them a staple in automotive and industrial NVH labs.

Industry use:
Powertrain NVH, pass-by noise, test-bench analysis


8. AVL Excite (Powertrain NVH)

Primary focus: Powertrain and driveline NVH

AVL Excite specializes in simulating and analyzing powertrain-induced vibration and noise. It is widely used for engine, transmission, and e-motor NVH—especially in hybrid and electric vehicles where tonal noise and high-frequency effects are critical.

Industry use:
Engine and drivetrain NVH, e-motor noise, torsional vibration


9. ACTRAN

Primary focus: Computational aeroacoustics and vibroacoustics

ACTRAN is used for high-end acoustic simulations involving airflow, turbulence, and structural coupling. NVH engineers apply it to wind noise, cooling fan noise, and external aerodynamic sound sources.

Industry use:
Wind noise, fan noise, aeroacoustic simulation


10. DIAdem

Primary focus: Data management and reporting

DIAdem is widely used to manage, analyze, and report large NVH datasets. Engineers use it to standardize post-processing workflows, compare test campaigns, and generate consistent reports for stakeholders.

Industry use:
NVH data management, reporting, test result comparison
