Vibration Auralization System Using High-Speed Vision

A new vibration auralization system is developed to support remote factory inspections. The system leverages high-speed vision technology to accurately capture and analyse low-frequency sounds outside the audible range, and selectively isolate and amplify certain sounds against a noisy background. Furthermore, the system converts these vibrations to an audible frequency range, making it easier to detect changes and anomalies in the vibration patterns, which can indicate issues with machinery or other equipment. The system also performs real-time fast Fourier transform to convert low-frequency sounds to a comfortable frequency band for hearing. The vibration auralization system was designed to accommodate the changes caused by the pandemic in the social structure, and the demand for new technologies to support inspections and monitoring. Experimental results demonstrated the system’s effectiveness in simulating low-frequency sounds and playing back circuit breaker sounds against a noisy background, demonstrating its potential as a valuable tool for remote inspections and monitoring in the manufacturing industry.
