We've all heard it the blowing winds howling through the trees past you etc. Question is Why does it make said noise? It doesn't sound like the bending of branches, movements or other objects or anything like that. (my daughter asked me and by gum i just didn't have an answer....anyone know?)

Velocity of wind causes noises. The strength in miles per hour has a bearing on the sound it makes as it passes. Even when there are no trees or obstructions the velocity alone causes sounds.The volume of air passing by a point is greater during heavy winds.

Leaves rustle in the wind because turbulent air on the downwind side of the leaf makes the leaf flip flop back and forth.
Wires and tree branches howl because air eddies on the downwind side build and release periodically at audible frequencies. If you could see the turbulence, it would look like a string of tiny swirls moving downwind from the wire or branch; the number of swirls per second is proportional to the pitch of the sound.

The wind can create vibrations as it moves around or over objects, high and low pressure areas (like it does moving over an airplane wing). Some of these vibrations will occur at frequencies the human ear can hear. It can create sound just like you can blowing across the mouth of an empty jug. Wind can create "galloping" in power lines where the vibration in the line matches some harmonic frequency and become reinforcing.

pressure becomes too great just like when you are in an airplane and your ear seems full
