Hi,

I am looking for a quick way to assess how much difficulty a hearing 
impaired patient has, based on audiometer results.

As part of this I have downloaded the SII software from sii.to
Can I use it to "score" a patients hearing loss, by ignoring the noise 
fields and simply entering the dbHL losses?

Is there are meaningful connection between the SII value and the hearing 
impairments scores given by the techniques such AAO-ACO-1979 / ASHA-1981 / 
Kryter-1998 / Wisconsin-1994 ?

What do YOU use to get a numeric value for a patients hearing impairment?

Is there now a single recognised algorithm to derive a hearing loss measure 
from dbHL values?

Thanks!

regards,

Richard
