My Grandmother was a Drama Coach and taught my mother how to do "Readings" I learned from her and to this day I believe being read to is valuable and reading out loud to children is priceless.
To help enhance the Audio learning there are some great products available beyond the already widely available book on tape and book on CD.
NetLibraryA commercial venture that does allow subscription accounts for libraries. The files are specifically intended to be downloaded and used by multiple users. The state of Utah has an agreement in place so that all Utah public libraries have access to a NetLibrary collection and patrons can download and check out an audio file for 3 weeks. This is my personal favorite of the bunch because they are free. And if I ever want to listen to a book again (or it takes longer than 3 weeks for me to finish) I simply renew it just like a library book.
Consider some of these sources for your audio learning.
