I was primarily addressing memory issues you referred to in your last post as well as alluding to Baddeley's model of working memory. I agree the auditory system is a whole different ball game,but using the brain's other capacities might fill in the deficiencies or gaps. Then again I might be suggesting other practical fixes your research is not concerned with.

Matthew, The short answer to your question is that the human auditory system is actually quite complex and doesn't follow very many easy rules of thumb. The problem is that humans, unfortunately, don't quite model the old Miller 7 + or - 2 rule for speech based recall, they measure it in seconds of recall, and the way humans understand language is complex and highly context dependent. And worse, the complexity doesn't end there, as masking effects can take place (characters embedded in the audio stream which have no relevance). Certain word choices have far more meaning than others, and prosodic cues (voice inflection), can also cause significant effects. So, making a good environment requires that you tackle all sorts of variables. Speed is absolutely important. Lots of other variables are important as well. It's pretty tough to get the mix "just right."
