Place a seashell, like a Conch shell, to your ear. What do you hear? The sea?
Now, while it might seem like we’re hearing the sea, in reality, we’re not – not even one little wave!
Remember that our ears are hearing lots of different sounds. It’s a very noisy world out there.
And an even noisier world inside us – like the beating of our heart and the whooshing of blood in our bodies.
Some people think it’s those swooshy sounds that you hear when you listen to a seashell – but that isn’t true either.
It’s all to do with sound waves. Sound waves come in lots of different shapes and sizes. Some will enter the seashell and bounce around – that’s called resonance.
Just to show there’s no magic you can try the same trick with a cup or a beaker – you’ll hear similar sounds. So I’m afraid that if you want to hear the sea, you’ll just have to take a trip to the seaside!
