00:00But why do we hear the sound of the sea in a seashell?
00:03At the risk of disappointing, the sound we hear in a seashell is unfortunately not the sound of the sea.
00:09Even if it is tempting to believe that a seashell is able to contain the sound of the waves,
00:14the sound heard by the ear of man is simply that of his blood vessels.
00:18Indeed, the blood that circulates produces a sound, even if it is inaudible.
00:23Stuck to the ear, the seashell amplifies this sound thanks to its resonance box effect.
00:29But the sound of the blood circulation can also be heard if you stick a jar of empty jam against your ear.
00:35Despite this reality, nothing prevents us from continuing to spread the legend
00:39according to which it is indeed the sound of the waves that we hear in a seashell on the beach.
