The velocity of sound in dry air is approximately 343 m/s at a temperature of 25 °C. Therefore, the reflecting object must be
more than 17.2m from
the sound source for echo to be perceived by a person located at the source. When a sound produces an echo in two seconds, the reflecting object is 343m away.

17 m
away, then after 0.1 second, the reflected sound or the echo is clearly detected. Hence, to hear a clear echo, the minimum distance between the reflecting surface and the observer is 17 m.
