Resumen:	As the years go by, UAVs become more accessible, their operation properties improve and companies like Embraer get closer and closer to apply this type of vehicles for their operations and become their future product. These vehicles are evolving fast and the possibility of skies being filled with buzzing multi-copters has raised major concerns about security, health and control. For this reason, a bast number of researches in the area of Aeroacoustics, need to be done to solve major problems as mentioned before, including problems such noise pollution in our modern society. Knowing this, the present work is dedicated to study a possible source of noise in UAVs, known as the interaction rotor airframe, which causes a tonal noise given by pressure fluctuations between these components. As a possible solution and based on some studies, were projected and manufactured three different airframes; each one with a distinctive noise reduction concept. To test these concepts an experimental process was conducted using a high definition microphone, as a data acquisition system to measure the different pressure levels through a determinate period of time and through a code in Matlab  interpret and plot the signals as a A weighting signal to identify a possible noise reduction in each case in the human acoustic domain.
