About

Henry E. Bass is a pioneering figure in industrial ultrasonics, whose foundational research has shaped our understanding of acoustic environments in manufacturing. His key contributions center on characterizing ultrasonic background noise—a critical factor for the reliable operation of ultrasonically controlled robots and sensors in real-world factories. In his landmark 1985 and 1986 papers (garnering 20 and 21 citations, respectively), Bass developed specialized high-frequency microphone systems to measure noise across the 0–1 MHz range. He systematically documented ultrasonic emissions from diverse industrial operations, including impact, bending, grinding, drilling, and laser etching. This work provided the first comprehensive noise profiles for these environments, enabling engineers to design more robust ultrasonic control systems and sensors. Bass’s research directly addressed the practical challenge of signal interference, offering essential data that continues to inform industrial automation and acoustic monitoring. His meticulous approach to quantifying background noise remains a cornerstone reference for researchers and engineers working on ultrasonic sensing in harsh manufacturing settings.
