Is it possible to stream music via the heating pipe?

As that crept into my head stupid/an asshole question. That is if you hit something metal in the heating pipe, the sound you hear where the pipe passes.
I myself am not a physicist, and now trying to figure out how it is possible for example to broadcast on the tube something more complex than a knock? Music for instance. And generally is it possible? Do not care for the quality and the echo is not the point.

PS the neighbors to not bother going, just curious...

You invented something like this -
Not only for glass/table, and for the battery.
On the battery would work too, if at least part of the surface smooth. - fletcher.Labad commented on July 8th 19 at 16:08
