Hearing AIds

I am new to this. While looking for information I came across a great booklet
on HLAA web site. www.hearingloss.org
click on purple box Materials
and you go to "The Consumers Guide To Hearing Aids. They compare dif
manufactures and aids in Conventional Analog, Entry Leverl DIgital, Basic Digital, Advanced Digital, and Premuim Digital
It helped me out in sorting out the differences. It also has a definitions of hearing aid terms.
It is a 24 page booklet date 2006/2007.
It cost less than $ 10 with postage.
I highly recommend it.
