Hi,

I have had a play with the hearing impairment calculator at: 
http://www.comdis.wisc.edu/facstaff/mrchial/HrgHdcp98.xls

This spreadsheet covers algorithms such as:  AAO-ACO-1979 v ASHA-1981 v 
Kryter-1998 v Wisconsin-1994

I have noticed that the calculated hearing impairment figures differ greatly 
between algorithms..

Can anyone please clarify what these measures are supposed to indicate - and 
why they might differ?

Thanks,

Richard
