Hmmm...I agree with Taylor. VERY hard. But lets add my opinion...
Bird singing: You pick a hard one first. Early morning birds singing, when there is minimal noise from the everyday world, is a beautiful sound. Maybe imagine it as being in a wide open field of grass and flowers. It is a tough one to explain. Crows, on the other hand, I just wanna shoot them. They are obnoxious. To me, imagine someone continously tapping you to get your attention, and you don't want to be bothered.
in a crowded bar: Picture the bar with everyone signing...same thing.
a jet flying above ya: Depends on how close it is. At the airport, it is not a pleasant sound at all, but you can hear and feel the power of it. When it is way up there, it is just a dull sound. Because of the delay in the sound, the sound is not coming from where the plane is, but where it was maybe 5 - 10 seconds ago...depends on how far it is.
kids' laughter: Innocence...that is all I can say.
lightning/thunder
istant thunder, just a dul rumble. Image your pager going off on the table for a second. You feel that slight rumble of it. Close by, it can be explosive type of crack. You probally felt it before.
waterfall: Depends on the size. Niagara Falls, its an awesome steady rumble. Image being in a 40 MPH steady wind. Smaller ones, just less roar.
doorbell: I guess I can try to describe the simple "Ding Dong" doorbell. Maybe picture a 2 lights, red, blue, and they just flash once each.
riding on harley davidson.. what do u hear?: Never rode one, but hear one going by, I wonder how they can stand the open pipes. Sometimes, they wake me out of my sleep. If I ever found one and found where he lives, I will go by his house and find a way to wake him out of his sleep.
Spice, you picked a hard question for us hearies to answer. I hope I could help you a bit.
