Luboš' comment really answers your question, but to more specifically address your comment:
The big difference between sound and light is that sound requires a medium to travel in while light does not. In fact light travels best in a vacuum where by definition there is no medium. The reason we can see back 13.5 billion years is because the light has been travelling through an almost perfect vacuum so there's nothing to impede it.
The problem with anything travelling through a medium is that no medium is perfectly elastic and there are always energy losses due to viscous damping. This is why when you strike a bell it may ring for a while but won't ring for anything like 13.5 billion years. You could ring the bell and wait for the sound wave to travel right round the Earth. You'd hear the sound about 120,000 seconds later, so this would allow you to hear a day and a bit into the past. However, unless it was an extraordinarily loud bell the sound would have decayed to below thermal noise in that time so you wouldn't be able to hear it.
This isn't really an answer to your question, but I mention it because it's cool: cosmic events like supernovae form shock waves when they hit ares of concentrated interstellar gas, and this is arguably a form of sound. In that case you can hear sound from many years ago, though you'd need an awfully big ear!
