Life would be simpler if her phone earpiece could be linked up to a loop
aerial that covered a wider area so that she wouldn't have to fiddle with
her hearing aid. Do any phones exist with the appropriate socketry to
allow them to be connected to a loop-aerial amplifier? She already has a
phone with a built in inductive coupler but that's not a lot of use with
the old chest mounted amplifier that she uses.

Try the RNID, Royal National Institute for the Deaf web site or ask them.
