which straight talk phone has the loudest speaker volume

[AC Question]

I am hearing impaired and I need a straight talk phone that allows me to hear the ring tones and the person I am speaking when I place or receive a phone call. I have a smart phone currently but even with a volume boosting application I cannot hear it ring or hear the person speaking to me which essentially makes it pointless for me to use it as an actual phone. The problem I am having is I don't know how to search the straight talk website or the walmart website to find a different phone that would have a built in higher speaker volume level.

I found a good article on the internet about what phones hearing impaired folks should get....
