This afternoon Maple have been learning how to measure sound in decibels. We measured the sound levels made by a variety of musical instruments using a sound meter and recorded them in a table. We then used the results to draw a graph. Did you know the loudest burp ever recorded measured 109dB – that’s not far off the loudest dog bark ever recorded at 113dB!
