Sound Dynamics

NVH Development

  • Benchmarking & assessment
  • Vehicle noise & vibration measurement and data analysis – engine, road and wind noise
  • Intake & exhaust development – exhaust sound quality
  • Exterior noise – legislative drive by and sound quality

Active Noise Control

  • Lotus Engineering has over twenty years of experience in Active Noise Control (ANC) technologies
  • External Engine Sound Synthesis (EESS) improves pedestrian safety for H&Evs and addresses minimum noise levels for ‘quiet’ electric vehicles
  • Creation of Internal Engine Sounds Synthesis (IESS) that are independent of exterior noise to improve the in-cabin experience.
  • Road Noise Cancellation (RNC) and Engine Order Cancellation (EOC) give greater control over refinement and can minimise undesirable low frequency noise
  • ANC can replace conventional NVH solutions, which are in general complex, heavy and expensive

Value-add that Lotus can provide

NVH assessment, noise evaluation and vehicle development to achieve low noise targets and high level of refinement

Implication of active noise technology to provide optimum NVH solutions and sound enhancement
