Comprehensive Testing Solutions for the Automotive Industry

Noise vibration and harshness (NVH) testing combined with acoustic imaging and multichannel acquisition all play a crucial role in identifying and mitigating sources of unwanted sound and movement within a vehicle.

The Importance of NVH, Acoustic Imaging, and Multichannel Acquisition

NVH impacts everything in a vehicle, from driver comfort to regulatory compliance. Excessive noise and vibration can contribute to fatigue, reduce the lifespan of your vehicle and ultimately compromise safety. By conducting in-depth analysis, manufacturers can optimise acoustics and refine performance, enhancing both customer satisfaction and overall vehicle longevity. Additionally, acoustic imaging provides a powerful method for visualising sound sources, while automotive multichannel acquisition ensures high-precision data collection across multiple sensors for an in-depth understanding of noise and vibration behaviour.

Industry Standards for Automotive NVH and Acoustic Testing

Automotive testing is governed by strict standards, ensuring that vehicles meet performance safety and environmental guidelines. Organisations such as ISO and SAE provide guidelines on acceptable noise and vibration levels, with compliance ensuring consistency across manufacturers. Meeting these benchmarks is essential for achieving regulatory approval and maintaining an advantage in the competitive automotive market.

Key Testing Methods in Automotive Engineering

A comprehensive analysis incorporates multiple testing techniques to assess sound and vibration at different points in the vehicle. Some of those methods can include:

• Engine Vibration Measurement – Identifies irregularities in engine function that may lead to performance inefficiencies or mechanical failure
• Motor Vibration Monitoring – Essential for Electric and Hybrid models ensuring a smooth operation and reducing unwanted noise
• Acoustic Imaging – Used to visualise noise sources and pinpoint problematic areas within the vehicle structure
• Multichannel Acquisition – Collects data from multiple sensors simultaneously to provide a complete view of noise and/or vibration behaviour across the drivetrain and chassis
• Advanced sound source localisation – Utilises sophisticated algorithms to track and analyse unwanted noise with high precision

Equipment for NVH, Acoustic Imagine and Multichannel Acquisition

Accurate testing requires advanced measurement tools. High-precision accelerometers, microphones and acoustic cameras play a fundamental role in detecting and analysing noise and vibration levels. These instruments help engineers fine-tune vehicle components, ensuring that noise levels remain within specified tolerances while enhancing comfort and durability.

The Role of Acoustic Imaging and Multichannel Acquisition

Acoustic imaging is revolutionary within the automotive industry; it enables manufacturers to detect and resolve noise issues with unprecedented accuracy. By converting sound into visual data, engineers can pinpoint noise sources and develop targeted solutions. Meanwhile, multichannel acquisition systems provide real-time, synchronised data collection from multiple input points, allowing for detailed analysis of noise and vibration levels within the vehicle.
