In other words, the feat doesn't affect the sounds. It merely allows those sounds to be used instead of the normal sounds a druid would make. Hence, the sounds that a wildshaped druid makes can be no different, and no louder than the sounds that a normal animal is able to make regardless of whether they are spellcasting or not.
As a result, a wildshaped druid casting a spell is no easier to hear than any other creature of the form he has taken. If that form is small and has a very quiet voice, the wildshaped druid will be equally quiet when using that voice.
Hence, your proposal that a druid in rodent form is "just as easy to hear as a human caster" is proven false by the RAW.
Heh, and by that interpretation, a druid wildshaped into any of a number of animals suddenly finds his spellcasting is much more audible than it used to be. Creatures miles and miles away can tell he's squawk-chanting, or howling out some spell.
Cuts both ways.
