I have a question too, wouldn't you want to separate their hearing loss
into a low frequency and high frequency component and then explain the 
importance of each band for speech information ??

Or what about a severe high frequency SNHL with basically normal
thresholds up to 1500/2000 compared to a flat loss of 45 dB,
depending on which way you look at it it could be a 40-50% loss
(based on the 50dB = 50% loss) but they are different.  
I know it is a counselling issue but would like some feedback!

Also instead of explaining the decibel and explaining what a
log scale is to your patient do many of you use some sort of 
percentage scale or, do you explain it in terms of severe profound,
etc.

Thank you for your support,
