Well only if you are a spirit or a ghost. In order for you to talk you have to breathe. And in order for you to breathe you have to have air. So, no if there is no air in the room people cannot hear a word you are saying.
when we talk from a long distance the air in the atmosphere will break the voice so we cannot hear
Sound travels through the air in vibrations, which can pass through walls and doors to reach our ears in another room. These vibrations cause the air molecules in the room to move, ultimately allowing us to hear the sound even if the source is in a different location.
When you hear yourself talk, most of the sound that you hear passed through the bones of the skull, not the air. These bones have resonances and act as filters changing the sound that arrives at your ears. When you hear yourself talk on a recording the sound passed through the air and is unfiltered, this is what other people hear when you talk So in fact you sound normal on the recording (as others hear you) and wierd when you just hear yourself directly. You just aren't used to hearing how you really sound.
Sit on their grave and talk to the empty air around you, hoping they can hear you.
The concept is that the mechanical helmet processes his air and the "breathing" you hear is the release or admission of air.
The reason people use air conditioning is to cool a room by cooling the circulating air in that room
Because when you speak or even hear a recording of yourself you know what you mean by what your saying. From a physics point of view it's because the sound is travelling through different material for a shorter distance. When other people hear you, the sound waves have vibrated through the air and diffused somewhat into the surrounding area. When you hear yourself talk, the sounds are traveling at you from outside in the air, and reflected back at you, but also through the flesh of your head, directly to your ear mechanisms. This can make you interpret the sounds differently than another person would when you talk and make you sound different.
you can only hear the air as wind
Air is less dense than say water. When you talk under water it is difficult to hear what is said because water has more atoms than air.
When you talk you hear your own voice. Therefore you're listening to yourself talk, so the answer is "Yes, you can talk and listen at the same time." yes we can talk and listen at a time
Sound waves can travel through the air and reach your ears even if you are standing outside a room. The sound waves can pass through the cracks and gaps around the door, allowing you to hear sounds from inside.
Sound is a compression/rarefaction wave in a material, such as air. There is no such thing on the moon.
