Recording from the middle the middle of the short road tunnel in Ribeira, Porto. The tunnel is completely tiled and has cobblestone pavement, so the traffic noise is reflected from all sides and mixes up to a big, almost constant stream of hiss noise. Only when the cars pass directly in front of the microphone you can distinguish them from the rest of the traffic (for example the bus that is passing in the very beginning of the recording). In the middle (ca 1:13) no traffic is passing, so it gets a little more quite, but then traffic starts again. Autocycle passing at 2:03, honking from a car at 2:29.Recorded with Roland Edirol R-09 digital recorder and Edirol CS-15 cardioid-type stereo microphone.
