Discipline: Engineering, Applied Sciences



This study intended to construct a noise detector with a warning device that could warn the users to control the noise and be observant to the allowed noise level. It sought to address the efficiency of the device as regards the sensitivity to noise, operation, and output through a light emitting diode (LED) display. Experimental development approach and descriptive method were utilized in this study. The functionality of the device was evaluated by five purposively chosen engineers and engineer teachers and five students as end-users. Findings of the study showed that the device is capable of detecting noise that is beyond the allowable level and of giving a warning signal through a LED display.
