Have you ever noticed that your voice sounds so different when it is recorded and played back? Do you know why?

When you speak, sound can reach the inner ear by way of two separate paths. The first is through vibrating sound waves hitting your eardrum, the way other people hear your voice. Your vocal cords create sound waves that travel through the air to reach your inner ear. The second way is through the vibrations inside your skull set off by your vocal cords. However, as they travel through the bone they spread out and lower in pitch, giving you a false sense of bass. But when you hear a recording of your voice, it sounds distinctly higher as you’re only hearing sounds transmitted via air conduction. Since you’re missing the part of the sound that comes from bone conduction within the head, your voice sounds different than you think it should.
