Bernie,
You are right on with we have forgotten what the original sounds were like. Here’s a poor but example:
The pizza in New York is great, my favorite. After living in Florida and eating the pizza they make her --- for the last fifteen years I felt that they went from being fair to darn good. They finally made good pizza. I went back to New York a short while ago – reality hit me, I had forgotten what the real thing was.
