<< With the echo I assume the sound is being converted to heat/vibration when it is being absorbed in the wall. >>

Exactly, heat (molecular vibrations).

<< Is there an analogy for when a cable sees a matching impedance of how the signal is being absorbed? >>

Yes, the signal would be absorbed by a termination resistor that matches the cable impedance. The resistor would convert this signal energy to heat according to Ohm's Law.
