Doors and windows to reduce noise, considering that sound travels better through solids?

Probably because that is what we were taught to do.

Sound travels more effectively when it is through a single material, than when it has to transition between a solid and a gas.
Much of the energy of a sound wave travelling through the air is reflected by solid surfaces. The intensity of the wave is again reduced when it reaches the other side of the solid, as it is unable to impart all of its energy back into the air. Energy not lost to reflections, or transmitted as sound waves through the next material, is dissipated as heat.

Sound waves do travel faster through solid media than through air, this is true. Sound waves require a physical medium through which to propogate (unlike electromagnetic waves such as light which can travel through space in a vacuum). The closer packing of matter in solids allows for faster transmission of sound. With that being said, the surface of the window or door will serve to reflect or absorb the sound waves. The sound waves that get through may travel a tiny bit faster through the solid door, but a large portion of the sound energy will be lost.

What?! Sound usually travels much better through air than solids. That is why the sound is muffled or completely stopped by shutting the windows and doors. Take a class in physics.

In some situations that's true, but not in a house with spaces walled off by closures of doors or windows, sound can "travel better over conduit = not restricted by other sound waves, but sound outside of the conduit is muffled by sealing off the corridor for it to travel in, open it and it flows through amplified.

That is a load of sh*t.
If you close a door or window it actually reduces the noise.

Personally I prefer the fight fire with fire theory: or in other words I like adding my own noise as an attempt to block out someone else's.
If you have ever lived in a dorm or an apartment no doubt you are familiar with this technique. If not the first answer you were given kind of hits it on the nose.

Tell you what, let me whisper something in your ear with nothing between us but air, and then I will stand outside and say the same thing through the closed window. You can decide which way is better.

because when you close the window the noise is REDUCED, try it and see, doof. This is an application where education actually makes someone less intelligent.

to reduce noise, pollution, security and for privacy
