Try this: Plug your ears with your fingers and speak at the same time. Notice what it does to your own voice? Imagine that with amplification. If you think it isn’t too bad and you can deal with it, by all means, try a set of ITE hearing aids. Realistically with appropriate venting, it shouldn’t be as drastic as the finger in ear test, but you will at least have some working knowledge of what they are talking about.
