Diseñar y construir un prototipo de sonómetro digital con ponderación de frecuencia A

Abstract

The present work of titulación proposes the design and the construction of a sonometer digital with weighting of frequency To, with the purpose of catching the different waves of sound and being able to quantify the amount of noise that is in our surroundings. Additionally, to complement the prototype's implementation, a programming tool known as Android Studio was used, which allows us to obtain a graphical interface to visualize the information in a simpler way. Initially, with the help of a musical recording studio and with different commercial sound level meters, in a controlled environment the comparative technical analysis and the different tests with the measuring equipment are carried out, and a study of the teams involved in the respective ones is presented. Field tests. On the other hand, the device that was implemented becomes the first, to be made with a stm32 card in the country, becoming a great contribution to the technology of our nation since in the future we could design a network that is used to measure noise at specific points in the city.
