Why enroll

Tyre/road noise and BSR are among the top NVH concerns in vehicle development, influencing customer satisfaction and brand perception.

This course will help participants master noise source identification, optimize tyre and chassis design, and apply advanced simulation and testing methods to tackle BSR at its root cause.

Whether working on passenger cars with quiet ICE (internal combustion engines) or electric motor-train, or performance or racing vehicles, engineers will gain practical insights to enhance vehicle NVH- refinement, and overall ride quality.

Course details

Ensuring a quiet and comfortable ride on rough roads is an important goal in modern vehicle design. Road irregularities often generate tyre/road noise and unwanted interior sounds known as BSR (Buzz, Squeak, and Rattle). Tyre/road noise occurs when the tyres interact with uneven road surfaces, creating vibrations that travel through the suspension and vehicle body into the cabin. Engineers control this noise by optimizing tyre design, improving suspension systems, and adding sound insulation materials.

At the same time, BSR noises are caused by small movements or friction between vehicle components such as panels, trims, fasteners, or joints. These noises become more noticeable on rough roads due to increased vibration. To reduce BSR, engineers carefully design component fit, use damping materials, ensure proper fastening, and test vehicles under different road conditions. By addressing both tyre/road noise and BSR during the design and development stages, manufacturers can provide passengers with a smoother, quieter, and more comfortable driving experience even on challenging road surfaces. 🚗🔧

Questions and Answers

A: —that's the most common mistake, blaming anything that makes noise at speed. The difference matters because cavity resonance tracks road texture and suspension modes, not engine load or discrete impacts. The symptom disappearing on smooth surfaces rules out bearing or latch issues, and exhaust boom wouldn't care about asphalt macrotexture.

A: —that's where people rush teardown. Temperature dependency is the tell here; you lose the failure if you don't reproduce the thermal state first. Shaker work and golden samples come later, once you've locked the real-world excitation and boundary conditions.

A: —that's the classic slip, treating it like a pipe. Tyre cavities behave like circumferential modes, not simple standing waves. Dropping the 2π term pushes you way off and leads to chasing the wrong suspension countermeasures.

A: —people hear 'buzz' and think aero. The difference matters because cold sensitivity points straight at preload loss and friction behavior. Wind and driveline effects don't selectively appear on cobblestones.
