• Developed an Acoustic AI system that analyzes subtle sounds from production processes and applies them to the Changwon EPS (Electric Power Steering) plant.

• AI technology tailored for manufacturing… Analyzing the operational sounds of products to inspect for defects at a rate of one per second.

SEOUL, South Korea, June 19, 2024 /PRNewswire/ -- Hyundai Mobis (KRX: 012330) has developed an AI system utilizing sound for quality inspection, which is now implemented in its production lines. This innovative approach leverages artificial intelligence to analyze the subtle sounds generated during product inspection to determine quality accuracy.

On June 18^th, Hyundai Mobis announced that it has recently completed a pilot implementation of an Acoustic AI-based inspection system at its Changwon plant, which produces EPS.

Acoustic AI represents a new generation of artificial intelligence technology, distinguished from generative AI, which relies on language for Q&A tasks. It remains relatively untested in the manufacturing industry.

The key to Acoustic AI is developing algorithms that assign meaning to specific sounds and facilitate appropriate judgments. Hyundai Mobis has invested significant effort in developing various AI-based technologies over the past few years, now showcasing production technologies specialized in quality control.

Hyundai Mobis plans to extend the Acoustic AI inspection system from the Changwon plant to other component production lines, prioritizing parts like braking systems that inherently generate noise due to their operational nature.

Choi Nak-Hyun, Vice President and Head of Digital Transformation at Hyundai Mobis, stated, "This initiative marks a pioneering example of process innovation not only in the automotive sector but across the global manufacturing industry. We will continue introducing differentiated AI-based technologies for production, R&D, and improvements in work environments."

While generative AI emphasizes versatility for general users, Acoustic AI is designed for industrial applications, especially smart factories. Its primary advantage is processing large volumes of tasks in a short time. The inspection system at the Changwon plant can detect defective products at a rate of one unit per second.

The Changwon plant produces approximately 1.3 million units of EPS annually. The production process includes 23 stages, from component assembly to vibration and noise inspection.
