NVH Testing for Electric Powertrains
Characterise, analyse and improve your system’s acoustic and vibratory behaviour.
From powertrain-level to subcomponent testing, we help you ensure a quiet, smooth and reliable driving experience.
Comfort is
performance too.
As electric vehicles become quieter, NVH issues become more noticeable — and more critical. At EPowerLabs, we perform NVH testing on electric motors, inverters, e-axles and complete powertrains to help manufacturers detect, analyse and correct unwanted noise and vibrations before entering production. Our NVH solutions cover both systemlevel and component-level testing, allowing for complete acoustic validation under controlled and replicable conditions.
What we test and why it matters
NVH performance is no longer a nice-to-have — it’s a key part of product quality and customer satisfaction.
With ICE noise gone, any rattle, harmonic or imbalance becomes more audible.
Our NVH tests allow you to validate and fine-tune your system’s vibratory and acoustic behaviour across a wide range of use cases.
Sound Pressure / Intensity / Power
Measure airborne noise levels of EDU and components
Vibration Order Analysis
Identify and isolate harmonic vibration sources
Random / Sine Vibration Testing
Simulate road and system-induced vibration scenarios
Modal Testing (Hammer / Shaker)
Analyse resonance and structural modes
Torsional Vibration Analysis
Characterise drivetrain torque fluctuations
Mount Vibration & Displacement
Evaluate EDU stability and support under load
NVH Dynamic Testing (Launch, Run-up)
Assess acoustic/vibratory behaviour in transient phases
Versatile Set Up
The test set-up can comprise single component or full eAxle system
Our NVH campaigns are run in a dedicated semi-anechoic chamber
using specialised e-motor and powertrain benches at our San Sebastián facility.
