Abstract
This project aims to measure the sound in different shapes of nozzles. It comprises a hollow wooden rectangular box, with different shapes of convergent nozzles, nozzles are made up of stainless steel sheets, wooden box is closed and sealed with acoustic foam and then a compressor is placed on the outlet mouth of the nozzle using valves. A sound sensor and Arduino UNO board are placed in the wooden box which in turn connected to the system which is installed with Arduino IDE Software. Total three shapes, i.e., circle, oval, chevron are tested by the equipment. Finally, we found Chevron shape nozzle is producing less sound compared to other shapes.
