Hi Tom,
the problem is obviously that unlike "silent", the word "ring"
contains the letter "g" which has a descender, as Steve explained
already.

How can you achieve that all braces have the same size?  There are
many possible solutions.  You could use struts or phantoms.

However, there is a very elegant solution.  All *tex programs except
Knuth's tex itself are using the eTeX extensions for a couple of years
now.

You are using \left and \right already, but eTeX provides a new
primitive called \middle.  See:

section 3.9 on page 12.
