    Conventional Noise and Vibration Testing

    Noise and vibration testing is widely used in product development, quality control and performance optimization to help engineers identify, analyze and improve NVH performance. For automobiles, industrial machinery and consumer electronics alike, it delivers critical data to optimize designs, meet regulatory standards and enhance user experience.
    Application Scenarios
    ■ Competitive benchmarking: Compare with rival products to optimize own designs
    ■ Fault diagnosis: Locate abnormal noise sources and analyze excessive vibration
    ■ Performance optimization: Reduce noise and block vibration transmission
    ■ Regulatory compliance: Pass noise certifications including ECE R51, ISO 362
    ■ User experience upgrade: Sound quality tuning, e.g., quietness optimization for premium vehicles
