Can you hear your own words if you are standing in a perfect vacuum? Can you hear your friend in the same conditions?

उत्तर
Yes, we can hear ourselves speak. The ear membrane, being a part of our body, vibrates and allows sound to travel through our body.
No, we cannot hear our friend speak as there is no medium (air) through which sound can travel.
