Thanks again Julie. In the past I have used hearing health foundation for research and will try again, especially through their Hearing Restoration Project. I am also trying to keep up with other research such as gene therapy. My voice distortion has gotten worse so I will start giving more time to investigating all possibilities. I am 88 years old and it definitely affects quality of life.

There must be other people with similar distortion (kazoo) like mine. Do you know of any good hearing forums where I can post?
