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