Can you hear noises through cinder block and drywall?

I live in a townhouse which is divided on either side by a cinder block wall. On the inside there is drywall. Every once in a while I hear a thump noise. It is fairly infrequent. We live by a busy street, and sometimes noises reflect, but this sounds like it's coming directly through the wall. Is it possible that even with cinder block I can hear my neighbor if they bump against the wall? I know if I hit my wall I hear the drywall resounding, but would that carry through?
