Mapping #3 and Audiogram

I had my third mapping appointment this afternoon.  I actually didn’t want to change my mappings (a rarity for me) and was glad when my audiologist said she wanted to do a sound booth test instead of mapping.

Here’s a bit of background before I explain today’s sound booth results.


This is from a post in April 2009:

The numbers at the top of an audiogram are the frequencies in Hz and the numbers on the left are the dB values.

Pink:  My residual hearing prior to surgery. You can see that it goes right off the graph and I basically had no high frequency hearing whatsoever.

Green: Hearing test with my hearing aids January 2009 when I was being evaluated for a CI. Those hearing aids were pretty cool. The aids more or less transposed all frequencies into the little pink area I had residual hearing in.

Purple: Hearing test with my CI.

Black line: Anything above this line is considered “normal hearing” which is between 0 and ~25 dB.

Red smiley face: I love that my audiologist put a smiley face there. :-D


I was born with profound bilateral hearing loss and was diagnosed at 20 months of age.  If you look at my audiogram from when I was 20 months and compare it to my audiogram from before I got my CIs (surgery damages residual hearing)…they’re exactly the same.  You also would not be able to tell which one was the left ear and which one was the right ear.  Residual hearing was the same in both ears.

When I was first diagnosed my audiologist used a jet as an example to help explain my hearing loss.  If I stood right next to a jet, I may or may not be able to hear it.  If I could hear it, it would be very quiet and difficult to hear.


Here are my audiograms from today’s sound booth tests.  The right ear (newly implanted) actually looks like it’s the “better” ear on paper.  Overall the right ear falls mostly in the 20 dB range and the left ear falls mostly in the 25 dB range.

Speech threshold (right ear–new):  5 dB

Speech threshold (left ear–old):  10 dB

My audiologist said these audiograms couldn’t look any better.  A 20-40 dB range is expected with CIs.  I was able to pick up all the tones at each frequency above the speech banana.

Blue:  Speech banana (frequency and range that speech sounds occur at)

Green:  Hearing test with right CI (new implant)

Pink:  Hearing test with left CI (old implant)

Hearing sounds and understanding sounds are two entirely different things.  Now, only if my brain would learn how to make sense of everything I’m hearing!  🙂

Pretty cool.  Kind of hard to explain to people that I’m profoundly deaf but I have “normal” hearing on an audiogram…but I don’t always understand what I’m hearing.  I hear a lot of what the average hearing person hears but I don’t process sound the same way which results in me still appearing “deaf” even when I’m “hearing” sounds.
