Well, not quite true.

If a blue whale is 31m long, it is a massive 15 500x bigger than this bug.

But it can make a sound of about 188 dB.  The thing is decibels are a logarithmic scale, not a linear one!  103 dB is twice as loud as 100 dB, 110 is 10x as loud, and 120 dB is 100x as loud...

So this means that while the Blue whale is 15 500x bigger than the boatman, it is over 10 000 000x louder!
