Well, honey, you can hear someone through a closed door because sound waves can travel through solid objects like wood. So, unless that door is made of some magical soundproof material, chances are you're gonna catch some juicy gossip or embarrassing stories being spilled on the other side. Just make sure you're not eavesdropping too much, or you might end up hearing something you wish you hadn't.
Hearing is a result of vibrations. The sound waves move through the air and vibrate your ear drum. The vibrations are translated by the brain as familiar sounds. Similarly, walls and doors resonate to the same sound waves and act like giant ear drums. By placing your ear to the door, you are effectively able to "transfer" those vibrations from the door (or wall) to your ear and hear, more clearly, what is happening on the other side.

It depends on person to person. If the work is which refreshes you, we will feel like doing it. Otherwise we feel very tired and try to avoid it.
Yes, for example: air is made up of several gases (78% Nitrogen, 21% Oxygen, 1% Argon, Carbon Dioxide, & Others) and sound travels through it. Otherwise you wouldn't be able to hear anything, just like in space where there is no gas, and no one can hear you scream.
Plant it, water it and then after 3 months it will have grown into a beautiful tree and when the wind blows through the leaves you will hear your answer.
It is possible to hear a teacher through a closed classroom door if the teacher is speaking loudly or if the door is not soundproof. The ability to hear through a closed door also depends on the thickness and material of the door.
You can hear it because of driffraction. The sound waves diffract through the openings.
Sound waves need a medium, like air, to travel through. When a door is closed, it blocks the movement of sound waves, preventing them from reaching your ears. This creates a barrier that reduces the transmission of sound and makes it difficult for you to hear noises from behind the closed door.
You can hear a teacher through a closed door of a classroom because the sound waves diffract or bend around corners. (Sound waves don't always travel in a straight line) Answered by: Nur _ _ _ _ _ _ Izyani
You can sometimes hear someone but not see them if they are behind a closed door, around a corner, or in a separate room. Sound can travel through barriers, allowing you to hear someone even if they are not in your line of sight.
Sound is not audibly louder in a room with the door open or closed. If I had a volume meter I might be able to measure the sound being slightly louder with it closed because the sound would reflect off a closed door but leave through an open one, but you'll never hear it. I determined this experimentally. First I closed the door to the room and played some Iron Maiden with my speakers turned up halfway. Then I opened the door to the room and played the same song at the same volume setting. It didn't get any quieter in there. The real effect, of course, is OUTSIDE the room. If I open the door and play Maiden, the neighbors hear it better than if I keep it closed and play them.
Maybe. Wooden doors are not generally "soundproof", so it's certainly possible that someone might, depending on how loudly you're whispering, how far from the door you (and they) are, how thick it is, and how good their hearing is.
The sound waves are diffracted through the door opening.
A normal, capable person can hear through their ears. The vibrations travel into the brain where they are decoded by one's knowledge of words and context.
Labrador Retrievers, like most dogs, have excellent hearing. They can hear any sound that you can hear, and many more in higher frequencies and lower volumes. If are able to hear something happening through a door, chances are your pooch can too.
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.
because a glass is like a micorphone you can here every thing
