It always amazes me just how loud sound is to our ears, even when the door or window is closed. How can dropping a ball cause so much disturbance that it shakes all the air and then all the atoms in the door, into our ear and still sound so loud! It just doesn't make sense, or does it?

Solids transfer sound better than air, because the molecules are closer together and vibrate in sequense easyer.

Actually the sound is much more likely to be coming through the gaps around the edges of the door than through the door itself. Sound is just a change in pressure... it makes perfect sense.

you are right.
Loudness of sound is directly proportional to the surface area of the vibrating body.
When a ball hits the door, the entire surface of the door vibrates .
Since the surface area of the door is quite big, hence loud is produced.
When some body calls you outside your closed door, you cannot hear this because it is not able to vibrate the door. But when some one knocks at your door, he is vibrating the door, and hence you can hear a loud sound,

soud travels faster through solid medium.as the energy is released in the form of sound it vibrates the particles of the material medium and the energy is transferred as waves. in a closed room there are 2 mediums for the sound to travel - 1. air 2.walls(solid). hence the energy transferred is high and simultaneous and therefore we tend to hear it as a loud sound more than an echo. hope my answer clarifies ur doubt.

The material of the door isn't enough to absorb all of the sound wave's energy. Because of this the door dampens the sound wave but then allows the unabsorbed energy to travel through it and vibrate the air on your side of the door.

Yeah you are so right!!.................this doesn't make any sense. So you can hear a ball dropping Through a closed door. Hell I can hear the neighbors fightin' next door through several closed doors, solid walls(there's and mine)and much more distance. I mean dude! This ain't exactly the discovery of the year ya know......but keep tryin'.

It travels quite quickly through air. Also, through closed doors, the sound waves can be diffracted through gaps in the door (at least I think so)

It makes perfect sense. Kinda like how 2 + 3 is always gonna be 5.

it does make sense. Because sound is heard more clear through solids than in air. This is because the solid molecules are closer to each others than air molecules. So when a molecule shakes it affects its neighbour molecule more than in air.
I hope you are convinced.

Sound get absorbed into different materials, such as the carpets, and wooden floors. its almost like it is filtered in to the room. Whereas a ball will bounce off and create a disturbance.
