Measurement of sound in different shape of nozzles by using sensor

Abstract This project aims to test sonicity using sensors in various shapes of the soil. It consists of a hollow rectangular wooden box, wooden panels in different sizes, an amplifier, a medication box and the program MATLAB. A compressor would be placed on the boiled panels. The wooden box is connected to the MATLAB software-installed systems by a microphone and micro controller. The device is evaluated in a total of three ways, i.e. circle, triangle, oval. Finally, we find that circular shape emits less sound than other types.
