Acoustics & NVH knowledge base
Published engineering analyses based on field experience. These pages explain the diagnostic logic and design decisions; confidential customer identities, datasets and commercial details are excluded.
Treating the highest measured SPL panel can miss the excitation path and modal coupling.
Panel participation, contribution ranking and transfer-path reasoning separate the source from the efficient radiator.

Panel contribution analysis isolated a 45 Hz access-plate response; two CAD ribs reduced the simulated contribution by 6 dB without added mass.
Read the published LinkedIn analysis ↗Mechanical shock and low-frequency exposure affect fatigue, visibility, reaction and long-term operator health.
Frequency-weighted acceleration, operating duty and input paths are assessed before seat, suspension or mount changes are selected.
Read the published LinkedIn analysis ↗High airflow, sharp duct transitions, fan tones and operator proximity can dominate an otherwise successful cabin target.
CFD/CAA identifies turbulence and vortex shedding; acoustic propagation and structural modes guide duct, lining, vent and mounting changes.
Read the published LinkedIn analysis ↗Background noise, HVAC flow and glass reflections reduce signal-to-noise ratio for radios, warnings and hands-free communication.
Microphone flow exposure, speaker directivity, reflection timing and Speech Transmission Index are considered during cabin design.
Read the published LinkedIn analysis ↗AHUs, fans, chillers and silencers must remove major heat loads without violating occupational or community noise limits.
Source spectra, low-frequency silencer performance, casing radiation and breakout paths are addressed before installation.
