Can You REALLY Hear The SEA In A SEASHELL???

We've all done it at one point of another, held a seashell to our ear to see if, as the old wives tale goes, we really can hear the ocean.

But what is it we are really hearing?

The answer - the sound of our own blood flowing through our head!

The design and shape of a seashell provides an excellent echo chamber to hear what is really going on inside our heads, but because of the myth and our expectations of hearing the ocean, that's what we fall into the trap of thinking that we're hearing really - we're really just listening to a psychological, preconceived notion, particularly because seashells come from the sea!
