a phone ring can be heard across a shut door because there is always some space through the door from where the sound travels and reaches to our ears.

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.
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 hear it because of driffraction. The sound waves diffract through the openings.
You can.
Yes, press your ear against said door. Courtesy of inside knowledge from Harvard M.D. Eavesdropping division
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.
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.
doorbell, knocking, see through peephole, hear footsteps, dog barking
because a glass is like a micorphone you can here every thing
no because sound travels through matter so the other person wouldn't hear you
Tell the other person to check their volume for you. Their volume might be off for you
