Can you tell us a bit more on what type of measurement is wind speed (and noise levels)? It it a continuous measurement or does it have different levels (low, mid, high)?

You can compare the graphs between the two data sets which will give you a good idea of the relationship between wind speed and noise. Assuming windspeed and noise are continous, scatterplot will tell you the relationship (linear, parabola, cubic??).

The sort of analysis you can use depends on the type of measurements you have.
