Vehicle NVH • Acoustic Engineering • EV Development
Quieter, smoother vehicles engineered with confidence.
Specialist noise, vibration and harshness consulting for OEMs, suppliers and engineering teams developing refined powertrains, electric drive units and complete vehicle systems.
Independent NVH Specialists
Acoustic insight from rig to road.
NVH testing, diagnosis and development support.
AVA Consulting helps engineering teams find the root cause of unwanted sound and vibration, then convert complex measurement data into practical design direction.
From early benchmarking to production sign-off, our work supports faster decisions, better refinement and improved customer experiences.
Data-led development
Objective measurements, subjective evaluation and clear reporting combine to identify structure-borne and airborne noise paths, tonal issues, resonance behaviour and customer-noticeable refinement concerns.
Built for modern vehicle programmes
Expertise across combustion, hybrid and electric architectures, with particular focus on e-drive whine, powertrain isolation, component validation, full-vehicle troubleshooting and acoustic quality improvement.
Root-cause diagnostics
Electric platform focus
Rig-based validation
Real-world evaluation

Vehicle NVH
Effectiveness of Soundproof Material on Heavy Motor Vehicle Engine
Soundproof material such as rubber sheets, plastic lining and soundproof fabric was used on a heavy motor vehicle engine. The drive-by noise was measured on a track and the results of various combinations of soundproof materials were reported.
EV Development
Dynamometer Vibration Investigation
Mysterious FFT peaks were measured at 600Hz -1200Hz during dynamometer operation. A series of measurements and modal tests were performed to investigate the cause of these peaks. Various possibilities such as misalignment, coupling methods, bearing inperfections, damper resonance were taken into account. In the end, the main culprit was identified to be the rubber wheels…
Component Testing
Gear Whine Noise DOE Investigation
After validating that the signature noise of various EDU designs are heavily dominated by gear noises. A Design Of Experiments process was initiated to determine the effect of gear imperfections, gear spline shapes and gear spline angles.
