The Consumers Guide to Hearing Aids
Today there are numerous types of hearing aid amplifiers and circuit configurations whereas there used to be only a limited number of options.
"The Consumer's Guide to Hearing Aids illustrates the various circuits and price options in a simple technology pyramid" reported one of Britain's leading Hearing Aid experts.
"The lowest step represents the lowest cost technology and the top of the pyramid represents the newest, more expensive technology."
This A4 32 page colour guide gives consumers the ability to compare hearing aids by brand, circuit option and model.
