When listening to music with headphones, why does yawning make the music sound like it’s had a temporary key change?


Thanks in advance.

In: Biology

Your middle ears are connected to the back of your throat by something called the *Eustachian tube.* This lies beyond your eardrum, and the purpose of the tube is to equalize pressure between the middle ear and outer ear.

When you yawn, that tube is temporarily opened, permitting air to move between the two places. When you do that, the pressure changes and that fluctuation changes how things sound, because sound is nothing more than rapid variations in air pressure.

When you yawn, it opens up the Eustachian tube which equalize pressure on your ear drums, causing a change in pressure, hence making sounds sound different
