Music Transmitted Through Your Skull Makes You Swim Faster
The first thing to understand is that your ears are not designed to detect sounds underwater. They work best at a certain frequency range (around 20Hz) and they don’t have much sensitivity beyond that. When you listen to music through headphones or speakers, those frequencies are absorbed into the speaker and converted into sound waves which travel through the air and reach your ears. Sounds above 20Hz will not be heard by your ears unless they’re very close together (like right next to them). Sound from 20Hz to 20kHz is called infrasonic, sounds above that frequency are ultrasound.
Ultrasound is a type of sound that travels at extremely high speeds – it’s so fast that it takes longer than light to travel between one point and another.
Sound travels slower underwater than it does above ground, but still quite quickly. If you’ve ever had an ear infection, you may have had a doctor put a tiny little camera into your ear and down into your eardrum. This is because light travels at such a high frequency that it cannot be seen by the human eye. The camera can see it though, and while the doctor watches the screen he can tell what’s wrong with your ear by seeing what’s inside.
