When a fruit ripens does the acidity level change at all or is just the sugars that hide the acid?

It seems that yes, the pH does rise (which means the acidity is dropping).

Gotta be honest, I just typed your question into a search engine and came up with some helpful articles on tomatoes (http://ucce.ucdavis.edu/files/datastore/234-1935.pdf), grapes (http://en.wikipedia.org/wiki/Ripeness_in_viticulture) and fruit in general (http://www.chemistry-blog.com/2011/10/12/fruit-ripening-how-does-it-work/)...

With grapes the acidity declines. I think this holds true for many fruits. Tannin levels may also drop in many fruits.

Indeed interesting.

I did read somewhere that lemons contain more sugar by volume than peaches though.

I'm not sure that is true but if it is, that would mean sour taste is not necessarily an indication of sugar level but sweet taste is a good indication of acid level.
