Why are some echoes not heard?

Is echo same as reverb?
Echo and reverb are almost the same audio effect except for one variance, and that’s time. Reverb and echo are reflections of sound in a space.Reverb is the same concept as an echo but with a smaller reflection time that often comes back within a second and conflates with the sound that hasn’t finished yet.
