Sound Pressure Level Measurement System in an Industrial Production Line Using STM32 Platform

In this work, conducted by three partners, called UFAM/CETELI, Envision (TPV Group) and ICTS, we present an embedded system, implemented in a lib, on the STM32 platform, for ambient sound level measurements in production lines. For factories, this measurement is important due to the need for factories to carry out regular sound level measurements to monitor environmental comfort. The results obtained, on average equal to $(62\pm 3)\,\text{dB}$ , were satisfactory for the target application.
