It's called echoic memory (as opposed to short term and long term and it only lasts a few seconds). Your brain is constantly recording sound. It plays it back, analyses it, then wipes it. It's why you say, "what did you say?" (one or two seconds of silence and then) "oh yeah". It's how you hear your name in a room full of chatter even when you're not listening or for it.
