Why enroll

With modern vehicles demanding smoother and quieter transmissions, engineers must master both simulation-driven design and real-world noise diagnostics.

This course provides deep technical insights and practical methods to reduce gear noise at the source and along its transmission paths.

Participants will benefit from industry case studies, hands-on methodologies, and state-of-the-art noise control techniques used by leading automakers.

Whether you’re in design, testing, or troubleshooting, this course will sharpen your ability to diagnose and solve gear NVH challenges efficiently especially for Electric Vehicles where otherwise quiet running is affected by a tonal gear whine ..

Is this course for you?

  • You work in Automotive or Mechanics & Turbomachinery
  • You're a Noise & Vibration Engineering / Mechanical Engineering professional
  • You have some foundational knowledge in the subject
  • You prefer self-paced learning you can revisit

You should skip if

  • You're looking for an introductory overview course
  • You need a different specialisation outside Noise & Vibration Engineering
  • You need live interaction with an instructor

Course details

Gear noise is a common issue in automotive transmission and driveline systems that can affect vehicle comfort and perceived quality. It is usually caused by factors such as gear tooth errors, misalignment, improper lubrication, or vibration during gear meshing. Diagnosing gear noise involves identifying the exact source using techniques like vibration analysis, sound measurement, and gear inspection. Once the source is identified, engineers apply control methods such as improving gear design, optimizing tooth profiles, ensuring proper alignment, and enhancing damping and lubrication.

Effective diagnosis and control of gear noise help improve transmission performance, reduce unwanted sound, and provide a smoother and quieter driving experience.

Questions and Answers

A: Chasing the wrong lever here burns time and risks louder part-load whine that customers actually hear. Reducing crowning can spike mesh stiffness variation at light loads, pushing static TE up even if full-load contact looks pretty. Rolling back some crowning and tuning at the dominant customer torque avoids amplifying the excitation instead of trying to bury it with bearings or housing hacks.

A: Picking the wrong mechanism sends you after filtration or washing fixes while the noise keeps climbing. Humid service with acceptable oil points to micro-pitting on the flanks when case depth or RA isn’t right, which roughens the surface and raises TE over mileage rather than causing sudden failures.

A: Skipping the signal chain or order resolution fails the test and guarantees arguments later. You need correlated order data under load, which means tach quality first, controlled torque second, and only then any subjective drive to anchor perception to physics.

A: Wrong choices here lock in noise you can’t tune out later or blow packaging. Raising overlap and matching microgeometry cuts excitation at the source, while grade alone or blunt stiffness changes don’t guarantee lower TE in the customer band.
