This is a 4.7k series resistor shunted each side by a 10 ohm resistor. So 
the attenuation is about 27dB not the 90dB on the label. A 1 volt signal 
comes out a few mV. Both plugs have the 10 ohm shunt. I can't see any 
difference to tell which has the series resistor.

Hearing aid companies really take one for a ride. Oticon sells a small 
clipon omni-directional microphone that I used with my hearing *aids* for 
something like $60, but Carolyn Wyatt told me it was the same thing 
RadioSnack sold for $15. We had a kind of friendship going, since we both 
knew a thing or two about the hearing aid industry, she from working with 
them constantly, me from Dad's work as medical advisor to Vicon Instruments 
and my Summer jobs there. I won't have this rapport with Advanced Bionics, 
not for a while at any rate.

I'm just going to go by RadioSnack tomorrow and just buy the thing. I can 
always return it if it doesn't do the job. I googled the part number and 
came up with a newsletter for the Oregon SHHH chapter. SHHH is Self Help 
for the Hard of Hearing, a nationwide rent-seeking group located in 
Bethesda, which published a bimonthly journal that I've been taking for 
many years. An article in the newsletter advised using the RadioSnack cable 
for a purpose similar to mine. There being only a small number of such 
cables, it's better for Advanced Bionics just to buy them from whomever 
supplied RadioSnack (and made them with a different color, as was the case 
with the Oticon microphone) rather than to have a very small number of 
specialized cords made just for the cochlear sound processor.

We (*I*) shall see (*HEAR*).
