The sounds we hear (rushing, whooshing noises, electric noises, voices (often tinny or high pitched), cracks, rattles, machinelike noises) are usually heard in the in-between state, in the pre-exit state. Once in the Astral 'proper' it seems to me that communication is done telepathically. Is this what you mean?

Also, I always hear what I call 'ear hiss' which is staticky, and that is always on. It's just more noticeable at night or in a really quiet situation. I'm not sure if this is what you're talking about, though.

Sometimes I dream of music, and when I wake up the music is my interpretation of the ear hiss that is always there, but magnified and 'orchestrated'. I'm not sure if this applies, but I guessed I'd just throw it in here.
