The reflection of a sound from a rigid obstacle which is heard seperetly from the original sound is called an echo.
The factors important for an echo to occur are:
i)The dist. between the source and the observer must be 16.6m or 17m.
ii)There must be a big sized building or obstacle it to reflect.
iii)The sound must be loud enough to be heard.
If it helps,mark as branliest ;P
