I am using  120 x one minute acoustic files ( according to "Guidelines for the use of acoustic indices in environmental research,  https://doi.org/10.1111/2041-210X.13254") to describe my soundscapes using the  maad.util.plot_features in python. This means I take the hourly average for my indices (ACI, NDSI, BI, Hf, ADI, AEI)  over a day. Additionally I plot the mean spl in each 1000 Hz frequency domain from 0-22000 kHz, for each hour over a day, with 

Can this method represent some characteristics (i.e the variations of selected indices ACI, NDSI, BI, Hf, ADI, AEI) for a day, by simply taking their mean value?
