I had found this interesting when it came out 2-3 years ago (http://www.shape.bc.ca/resources/pdf/noisehearinglossmusicians.pdf).
It is a nice summary plus, for those interested, it points to a large number of other researches (I can't remember which one had a very comprehensive discussion of how dynamics helps and the increased problems caused by the "db war" in popular music).
