You are right. Both, the sound events database and an SPL at known distances database can be sufficient. However I'm not sure if it is easy to access to this two databases and adapt each data or making myself the (calibrated) recordings. I think that I will need more than 100 sound events. How did you solved the problem of the ground traffic? Did you had to measure yourself the typical SPL at known distances? Thanks!
