@Soulfox -- That is not always the case. My ringtone on my smartphone is one that sounds a heck of a lot like an old time bell on a phone from the 1930s or so. If I didn't want that sound, I could pick something that sounds more digitized and modern.
The great thing about those simulated bells is that you can get something that sounds traditional or something that it far removed from tradition. These things can simulate darn near anything, so why limit yourself?
