I was doing a science test to see how the sound travelled over a distance. This is what I used: a wireless, some sticky notes, a pencil a decibel meter and a long long space. I put the sticky notes on the floor every 2 metres of the long long space. I put the wireless to a scruffely noise and walked to each sticky note and wrote down how many decibels the wireless was making useing the decibel meter. I had recorded the noise so I printed of a graph and the noise went down like it should. I think it went good but next time I will not make to loud foot steps and not cough.
