This project aims to measure the sound in different shapes of nozzles by using sensors. It comprises a hollow wooden rectangular box, wooden plates with different shapes, microphone, micro controller, Matlab software.The wooden box is closed with differently drilled plates and then a compressor is placed on the drilled plates. A microphone and micro controller are placed in the wooden box which in turn connected to the system which is installed with Matlab software. Total three shapes, i.e., circle, triangle, oval are tested by the equipment. Finally, we found circular shape is producing less sound compared to other shapes.
