when we cover our ears with our hands, we cant hear other sounds, but when we speak, with the hands covering the ears, we can hear ourselves. why?
We do able to hear ourself even when we cover our ears because our internal organs are inter connected in such a way that whenever we speak that stimulates the muscles of our jaws and generates a corresponding signal to our ear drums and as a result our ear drums react or vibrate accordingly and transport the information to our brain.
