Sources of error for speed of sound lab

[kamalholly]

Hi!
Last Week we did a Physics lab on Speed of Sound. Two wooden sticks were banged against each other at a distance of 100 m from the wall(Then we went to 200 m, 300m and finally 400m) and the echo was heard and time was measured using a stopwatch. It was a rainy day. Can anybody suggest me some sources of error for that lab? Thank you!

The largest source of error would definitely be the reaction time of the person in charge of the stopwatch. compared to this I would think that all the other errors are negligible.
