A lot can depend on the moisture in the air, and which way the breeze/wind is blowing. Both can carry sound.

About 30 years ago, a woman and her 8-9 yr old daughter were hiking, and the mother fell and broke her leg. The girl got back to the car and kept blowing the horn, three blasts and a pause, three blasts and a pause. Someone heard, and followed the sound to investigate. They would never have heard her yelling.
