Design and construction of a scanning stand for the PU mini-acoustic sensor

Abstract

The main objective of this work was to design and construct a device that would facilitate and reduce the intensity of work in the process of scanning surfaces with a Microflown PU Mini acoustic probe. Our proposed device will shorten the total time to scan the surface and improve the quality of data measurements. The device was designed to be able to perform movement along the X and Y axes, thus achieving scanning of the entire sound field. Some components of the device are manufactured strictly according to particular specifications to suit our requirements. The most important step in the design of the scanning device we prepared for the particular acoustic sensor was the design for the linear connection that fulfills a supporting function for the entire device as well as provides movement along the X and Y axes. The final step was the design for the automation of the entire system, for which we selected an Arduino Uno (ATmega328) controller. The actual device was tested in the final stages. The device is designed and tested as functional and able to work on what was intended for and is ready for further modifications or use in practice.
