Dear Dr. SerVaas: I am wondering if anybody among your readers can give me the address of a hearing helper called "The Wizard."When I was in the hospital, a woman from the office came in with this article--a black box with earphones. She put on earphones and I put on earphones, and I could hear every word she said clearly without my hearing aid, which is only half as good, if that!

There was no address anywhere, but she said they sold it in the gift shop in the last hospital she worked in for around $100.

I am very anxious to learn more about this wonderful helper and would appreciate any help you can give me.

I enjoy your column in the Post very much.
