We conducted a science experiment to see if sounds were fainter, the further away we came from the source.
We measured the playground out in 5m intervals. We had a timer and a chime bar. One person stood at the 5m line and their partner hit the chime bar. The person on the 5m line timed how long they could hear the chime. We repeated it for 10, 15, 20 and 25m.
We learnt that the further away we were from the source, the less time we could here the chime - fainter the sound became. We also discovered that other factors affected the results including outside noise and how hard the chime was hit.
