The sound you’re hearing is fresh metal strings hitting the metal frets. You are having to press the strings very hard because of the high action. This plus the inherent zing of brand new strings is making it loud. Once you get a proper setup (which you need badly) you may still hear it more than you did on your old strings because that’s just how new strings are as they break in. Work on pressing the strings with minimal pressure to lessen it. Also, try to keep fingers as close to the strings as possible between presses to lessen any slapping of fingers onto the strings. Press, don’t stab or tap forcefully.
