Audiogram question...CNM?

Hi there,

I got a copy of my most recent audiogram today. I generally have no problem understanding them but the one I got today at ‘CNM’ written on it at three different frequecies in both ears. This has never been written on one of my audiograms before. When I looked it up I was able to find that it means ‘Could Not Mask’ but I am not sure what that means in relation to my hearing, the audiogram, or anything else. Could someone please explan this to me?

Hi JennyB,

Considering your hearing thresholds that you have posted in the past it most likely refers to “could not mask” as the audiometer may not be able to output loud enough masking to be effective considering the extent of you hearing loss.
