Development of Portable Noise Detector Device with Vibration Mechanism and Light Warning Signal

Abstract

To assess the performance of a noise-detecting device, we conducted an experiment in the main library of the University of Science and Technology of Southern Philippines. The device was deployed on each table to detect different sound ranges: QUIET (below 50 decibels), WARNING (51-59 decibels), and NOISY (60 decibels and above). The results demonstrate that the portable noise detector effectively alerts library users about their excessive noise, relieving the need for repeated bell ringing and allowing staff to focus on more important matters. Furthermore, we conducted a survey among selected library users to evaluate the device's acceptability. The feedback from students was positive, indicating that they found the device acceptable and helpful. These findings suggest that the portable noise detector, equipped with a vibration mechanism and light warning signal, provides an effective solution for reducing excessive noise and notifying library users.
