Hidden Sound 7
This sound has a somewhat peculiar location, we recommend you listen at the intersection of Via Filzi and Via della Costituzione, but in reality it can be found almost all over the city!

It’s a loud “ROMBOSOUS” noise!
We recorded it in the morning on the bridge, however you can find it everywhere, because people are always going somewhere!
