An inquiry of a reference about loudness models

[Kaisu Krohn <kaisu.krohn@xxxxxxxxxxx>]

Dear Auditory list,

I would have wished to ask for your help in finding a certain reference. 
I heard from one professor of Acoustics about an article in which 
several loudness models for musical signals were tested. In this 
article, the authors came up with a conclusion that the loudness models 
didn't necessarily apply in all cases to musical signals since the 
models usually have been targeted for stationary wideband signals - such 
as continuous white noise or filtered noise. Unfortunately the professor 
couldn't recall the exact reference to this work. Would anyone of you 
know how to find this article? Also, other references related to this 
topic are of course very welcome!

Very many thanks for your suggestions!

Best wishes, Kaisu Krohn
