Yes, press your ear against said 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.
A closed door constitutes a physical barrier to the movement of air; an open door permits the movement of air.
my friend, You need either a Hotel or Classroom Security function lockset. Good luck : )
There is a magnet on the door of the fridge and this is attracted to the metal on the fridge. This closes the door. This method makes it easier to close refrigerator doors and also makes it more likely that you've actually closed the door.

through the door
Yes.
By walking down the hall and through the door?
If the door can be opened from the inside, as most classroom doors do, it is not illegal. You can get out by going through the door with no problem. If a teacher locked you in a closet that is another story, but most classrooms are kept locked from the outside today since the recent school shootings. In fact, in my school locked doors are now required.
One likely cause is sound wave propagation. When a teacher speaks loudly, sound waves travel through the air and can easily pass through the open door and down the hall, allowing the voice to be heard.
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.
When the door closed behind me, I realized that I had dropped my keys; I turned around to see them through the glass on the floor behind the locked door.
when a door is "closed" it can not be opened by pushing or pulling
You can hear it because of driffraction. The sound waves diffract through the openings.
