<br/><br/> Noise is considered as one of the biggest challenges in a university library finding the right<br/>balance between accommodating different study styles and maintaining a quiet space for<br/>focused work. Unfortunately, university library in colleges have hard time in monitoring<br/>noise due to the lack of noise monitoring system and it is the reason why the noise in<br/>university library is increasing. There are several technologies used to address the lack of<br/>monitoring such as recorded voice for warning, decibel value appeared in a lcd monitor,<br/>surveillance camera and the main component is sound sensor. However, the accuracy and<br/>reliability of sound sensor remain challenging in terms of practical applications. This<br/>project study aims to design, develop, test and evaluate the noise monitoring system. The<br/>researchers utilized the prototyping approach and tested the system in terms of accuracy<br/>and timeliness, engaged 20 respondents to evaluate the system based on ISO 25010:2011.<br/>The researchers found out that there is a significant difference in accuracy between analog<br/>sound meter and noise monitoring system, based on the (t (15.359) + (df)=4.146;<br/>p = <.001). Meanwhile, based on the independent T-test results in timeliness (t (20.726) +<br/>(df)= -2489; p = 0.11) and appears that there is no significant difference. Lastly, the<br/>respondents evaluated the system as “Very Good” in terms of reliability (x̄=3.75),<br/>performance efficiency (x̄=4.18), compatibility (x̄=4.21), maintainability (x̄=3.80),<br/>functional sustainability (x̄=4.17) and “Very Good” in overall result (x̄=4.02). Overall, this<br/>research offers innovation and insights into noise monitoring and propose a bright solution<br/>with its automated recorded voice. Faculty members and students found out that the system<br/>is excellent based on ISO 25010. The project study's outcome is intended for managing<br/>library services and particularly helpful for library staff and students, and it contributes to<br/>United Nation Sustainable Development Group 4, 9, 17.<br/>Keywords: Innovation, Partnership, Quality Education UN-SDG #4, 9, 17
