The aim of this project is to find the correlation between turbulence intensity and acoustic noise level. To achieve this aim a test was performed on the 5th of April 2012 in the acoustic laboratory of the Technical University of Łódź. In this project we are going to explain, how the test was performed, which data we obtained, and which results we got after having analyzed them. The project has been divided into six parts. The first one is a little introduction. The second one is about sound and noise fundamentals. In this part we are going to talk about the noise and sound concept and about how to do the appropriate measurements. Afterwards, at the third part, turbulence concept will be developed. This part has been divided into nine parts including the turbulence definition or how to measure turbulent flows. In the fourth part, it is possible to find a general description about the test performed and the characteristics of the all equipment required. Next part is the data analysis. In this part the data have been treated for finding the correlation later, in the next part. So, in the part sixth, the correlation between turbulence intensity and acoustic noise level has been found. Finally, in the last part, the results have been interpreted.
