That’s strange, in the compressed version i have the levels reading here at about -3db & in the newer version i have it reading at -6db. Does loading it into adobe premiere making it automatically louder by any chance?
Here’s a third pass at it just incase the s’s are just being very harsh overall & Incase you want to use it, i did a slight de-esser on the whole file, it helped bring down alot of the hiss
