 >First we clapped at different distances to the sensor in order to measure from how far the sensor Will pick up >sound. We soon realized that the measurements were very inconsistent as it is impossible to make two or more >identical claps in a row.

 >To compensate for the inconsistency we decided to use a smartphone and transmit a constant tone. The setup is showed >in the picture below. The car was placed on a table in the middle of the room and loudness were measured from >different distances:
