Yes they do. That’s what an echo is, sound waves bouncing off an obstacle between two points. That obstacle doesn’t need to be within the direct line of sight, just within the dispersion area of the outgoing sound wave.
At the far end you’ll hear (although in reality, your brain will almost certainly cover this up for you) distortion caused by the sound wave defracting off the obstacle and interfering with the primary wavefront. Hence the reason why people put so much effort into design concert halls, and adding sound dampening treatments to recording studios. Obstacles will distort sound, but energy absorbing obstacles will distort less.
