Why does your Recorded Voice sound different?

Last updated on September 11th, 2020 at 12:22 am

Have you ever witnessed the bizarre sound of your voice when you hear it in a recording? Well, all of us must have experienced this at some point or the other with our recorded voice. But, do you know the reason behind this? Let’s find out.

How do we hear the sound?

The ear’s hearing mechanism lies deep within the inner ear. Sound reaches
the inner ear in a couple of ways. Most of whatever we hear are the result of
air conduction. Things that make sounds cause sound waves that are transmitted through the air.
Those sound waves reach your outer ear and travel through the eardrum and middle ear to the cochlea. The cochlea is a fluid-filled spiral organ in the inner ear that further translates those waves to the brain. But the air isn’t the only way sounds reach the inner ear. The bones and tissues inside your head also conduct sound waves directly to the cochlea.

Speech Voice Vs Recorded Voice

While speaking, your vocal cords create sound waves that essentially travel through the air to reach your inner ear. However, the bones and tissues in your head also conduct
those sound waves directly to your cochlea. So the voice you hear in your head when you speak is the result of both methods of transmission.

When you hear your voice on a recording, you are only hearing sounds transmitted via
air conduction. Since you’re missing the part of the sound that comes from bone conduction within the head, quite obviously your voice sounds different to you on a recording.

When you speak and hear your own voice inside your head, your bones and tissues in the head tend to enhance the lower-frequency vibrations. This means that our voice usually sounds fuller and deeper to you than it really is. That’s why when you hear your voice on a recording, it usually sounds relatively higher and weaker than you think it should.

Hence, don’t worry if your voice sounds funny to you on a recording. Everyone experiences the same thing. Just because it sounds funny and different to you doesn’t mean other people hear it that way. What you hear on a recording is what they’re used to hearing all the time!
