br Prototype for monitoring noise pollution as a tool for the empowerment of society

Objective: Acceptable levels are between 45 and 65 dB according to the OMS, exceeding these values can affect mental and physiological health, deteriorating the quality of life of the inhabitants. The purpose of this research is to identify the levels of noise pollution in the historic center of the city of Popayan, Cauca, Colombia, during peak hours of midday. Method: Applying the Design Thinking methodology, a prototype based on the Internet of Things (IoT) and a mobile application were designed to monitor the acoustic level in real time, and thus offer a technological tool that contributes to the empowerment of society in relation to its environmental conditions Results: Results: The software solution was developed for Android mobile devices, in operating system versions higher than 6.0 (Marshmallow), using tools such as Android Studio and Firebase. As a perspective of this work, it is suggested to make measurements for longer periods of time, and in several places in the city. Conclusions: Real-time measurements of the level of noise pollution, for example, through the application and measurements made during 9:11 A.M. and 6:31 p.m., on February 11, 2022, it was possible to deduce that the average level of noise pollution was 61.48 dB and that, in the measurements made in the morning, they were the ones with the highest levels of pollution. , being the data of 11:01 A.M.
