Smart Sound-level Control System for Libraries: An Innovation for an Enhanced Learning Environment

Abstract

This study aims to develop an intelligent sound level management system for digital libraries to mitigate noise disturbances and optimize learning space management. The innovation features an automated noise monitoring and alert system, utilizing an Arduino Uno R3 microcontroller integrated with a calibrated KY-037 sound sensor, complemented by physical spatial zoning. The findings indicate that this innovation significantly enhances operational efficiency. The system demonstrated high levels of accuracy and reliability (Mean = 4.27) and responded rapidly to fluctuations in sound levels (Mean = 4.64). Furthermore, the implementation effectively reduced noise-related complaints among library users, resulting in the highest level of user satisfaction regarding the learning environment (Mean = 4.73). Consequently, this system serves as a strategic tool for maintaining service quality and fostering a sustainable academic atmosphere.
