Yes, making noise was key in locating my underground PVC. In my
case,
I was able to locate the end by listening closely NEAR where I thought it
should have been while someone else was running a snake fully inserted in
the pvc back and forth a few inches.... the noise it made at the last
sweep was evident with no other background noise to interfere with it.

Congrats!

That's probably the best answer, as you are going to fish something or not
and it's always more expedient to use the most handy tool first before
hauling out the hardware store or the drawing board. This is how it usually
plays out, that there is plenty of noise when you are trying to bang the
fishtape past the 90's. This is how I learned to use 45 degree sweeps and
pull boxes at every opportunity. Anything to avoid the frustration of
breaking wire or fish tape and wasting my own time.
