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
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.
Sound waves are able to travel through solid objects, such as doors, through a process called transmission. When sound waves strike the surface of the door, they cause vibrations which are then transmitted through the material and can be heard on the other side of the door. The door does not need to be completely airtight for sound to pass through it.

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.
To represent Ben's total distance traveled to the classroom door, you can create a simple table with two columns: "Segment" and "Distance (m)." The first row would show "From Desk to Teacher's Desk" with a distance of 2 m, and the second row would show "From Teacher's Desk to Classroom Door" with a distance of 3 m. The total distance Ben walked would be 5 m, which can be noted in a third row labeled "Total Distance."
when a door is "closed" it can not be opened by pushing or pulling
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.
A magnet can be used to keep a door closed by attaching one magnet to the door and another magnet to the door frame. When the door is closed, the magnets will attract each other, creating a strong force that keeps the door closed.
You can hear it because of driffraction. The sound waves diffract through the openings.
