Um sistema de monitoramento de ruído em ambientes de trabalho

Abstract

There are a lot of silent males in society who can do harm in the long run, one that is well underrated is noise. Every day we live with the most diverse types of noise, both at work and outside. Taking it to the work context, there are many places that do not provide support for good acoustic health, and this in the medium and long term can generate various harms for a person, such as headaches, tinnitus, despite the intensity of the noise that the person is exposed, sleep disturbance and even loss of hearing. This work basically has two goals. Show the real importance of sound health in work environments and provide a system capable of showing in real time the noise level of a given location in decibels. Noise is captured from a cell phone microphone and sent over the local network. For network communication, web sockets technology was primarily used, which is a different way of asynchronous communication over the HTTP protocol. The system also keeps some data about noise for reports and issues alerts that are made via E-mail or Telegram, where the interval of these alerts is configurable, as well as the level of decibels needed to trigger this alert. According to surveys carried out after using the system, it was understood that people really agree that sound health is important, and that the data provided by the system will serve as a scientific basis for possible changes in the places where the experiments were carried out, and in the assembly of new environments that may be created, so that they are already thought of the acoustic issue according to each type of work.
