Abstract
The noise from magnetostrictive ultrasonic generators and its physiological effects on employees working in an area where these units are operating is included in the projects that the Science Departments of St. Ambrose College have been investigating for Pioneer-Central Division, Bendix Aviation Corporation. Periodic checks have been made since January 30, 1956, using a Maico Model F1 audiometer operated by Professor Lester Schaeffer, St. Ambrose College Speech Department, on a group of 36 individuals associated with the Engineering Section of Pioneer-Central. These individuals are divided into three groups: (1) constantly exposed to ultrasonics during working hours (engineers and technicians working in ultrasonics laboratories); (2) occasionally exposed to ultrasonics during working hours (sales engineers and drafting personnel in ultrasonics department); (3) never exposed to ultrasonics (engineers and management personnel in other sections of engineering). The report submitted is in the form of a chart comparison of the hearing ability found for these various groups.
