Abstract: The use of a tapping machine in four specific configurations is required in the determination of the FIIC rating of a floor-ceiling assembly as prescribed in ASTM Test Method E1007, as well as in the laboratory IIC measurements prescribed in ASTM E492. When performed with presently available equipment, the procedure requires either two acousticians be present -- one taking measurements i... read moren the room below while the other moves the tapping machine to four required positions in the room above -- or one acoustician who must return to the tapping machine on the floor above after taking each measurement below. The objective of this work is to design an automated testing system using National Instruments myRIO robotics components to be retrofitted to an existing tapping machine. This allows for wireless control of the position of the tapping machine from the floor below, allowing a single acoustician to perform the test more quickly. The prototype was tested for accuracy with varying levels of weight and the positional error was measured using an on-board webcam. Overall, the error in the movement of the prototype is not statistically significant (alpha = 0.05), indicating little sensitivity of the system to changes in weight, but requires future work for further increased accuracy.
