Abstract
The noise pollution is one of the main problems in the world, mainly related to the growth of urbanization. In function, the noise exposure can provoke diseases for people who are exposed for a long time, and many times they do not perceive the danger. According to the Telecommunications International Union, approximately 7 billion people have been using mobile and almost half have internet access at home, then it is possible to verify the fact that the smartphones are the main tool for facilitating many human tasks. Besides, studies of acoustic should be orientated in this way, mainly to give more facility for people for using their cell phones without large difficulties. Aiming to fulfill a preliminary study about application uses for measuring sound pressure levels, the comparative analysis was undertaken among the outcomes obtained by the normalized meter and the smartphones, following the NBR 10151 requirements. These apps were selected through some criteria, as follow: users’ evaluation, the capacity of measure in A-weighted filter and in the fast mode measurement configuration. Therefore, pressure sound level results were measured through different modes and compared each other for verifying their capability to make measurements in daily situations, without a standard meter.
