Hello Lily's Parents,

I'm a speech language pathologist, not an audiologist, but I work with deaf kiddos. Their audiologists like to remind me that very commonly the little guys (under 7, but especially under 3) hear quieter sounds than they respond to. I would argue that Lily DOES hear more than she responds to, because her speech recognition thresholds (SRTs) were lower than her speech awareness thresholds (SATs). It should be impossible to recognize speech at lower levels than you are aware of speech. :)

Awareness means you can barely hear it. Recognition means you can barely understand what it is. The SAT is usually 10-15 dB lower than the SRT, according to this: http://emedicine.medscape.com/article/835840-overview (I didn't know actual numbers, so I googled it--the article is by a PhD audiologist, so probably accurate.)

So if her SRTs are 20-25 dB... her SATs might be 10 dB? That's what Dr. Smoski seems to imply. And an SRT is going to be more reliable than an SAT, since it requires the person to repeat the words rather than just show that they heard something. But of course I should give a disclaimer: "I have never met Lily, and I have no idea what any of her audiological parameters are. This is supposition." :)

Whatever the numbers are, her language and listening progress has been so wonderful that I don't think I would change a thing. Congratulations on having a little super star CI user in your very own family. And to top it off, she's just adorable!
