Sound can travel in air at approximately 340 meters per second.  i.e. 340 millimeters per millisecond.
Let's check it up by mezzo-piano pizzicato!
Actually, top-plate of cello needs to be moved and compress the air, it might be needed 2 to 3 milliseconds.
In this measurement, 3 microphones were not the same model.
However, oscilloscope shows somehow the most likely delays.
