Why do we sound different in our heads?

So there is nothing worse than hearing yourself back on a recording… but why is it that we sound so different?

The sounds we hear are waves of pressure that move through the air, when these sound waves reach our ear they travel down the ear canal and strike the ear drum, this starts to vibrate. The vibrations travel to the inner ear where they are translated into electrical signals which are sent to the brain.

So why is it so different? The inner ear as well as processing sounds from outside the body, it can also be stimulated by vibrations that travel through the body. So when you talk you hear both sets of vibrations, you hear the sound from your mouth combined with the transmitted vibrations that travel from your vocal cords. Bones in the neck, and your skull help to enhance low frequencies, so in most cases you tend to sound deeper in your head than on recordings.

    Now I know why my voice sounds so much higher in recordings! I knew it couldn’t all in my head after all… (well, actually it is.)
    Thank you Jack for writing a technical blog post without the unnecessary use of incoherent jargon.
