A young child laughing.
A flowing stream or river over rocks, that's the best natural sound. Best man-made sound would have to be the sound of a piano.
A puppy attempting to howl.
I agree with Gator.......
The sound of laughter from a baby/child.
I'm with Gator on this one. Nothing is sweeter than a child's laughter.
When you call your dog and you hear the little pap pap pap of their feet. Also, music.
Rain falling on a cotton tent when you are snuggled down inside.
The sound of any one of my grandkids' voice saying "I love you Pappy."
Children playing in the sprinkler and laughing when they get wet.
The water rushing over your toes on a sandy beach.
At the end of the day, when the household has been put to rights, everyone is fed and tucked away, the silence that descends in the house is a wonder to behold.
Life its self.
chirping of birds early in the morning!
the best sound that ive heard until now!
