Welcome to the site. I drove an 04 Prius (the first year of the current hatchbach style) for two years. I never noticed any strange changes in the noises produced by the car during its various phases of operation. That doesn't mean, of course, that something's not happening with your car.
Noises are notoriously hard to pin down. It will be a lot easier to tease out if: 1) you can be more specific about exactly what you're hearing, 2) you actually get an MIL (malfunction indicator lamp) on (the dramatic red exclamation point in a Prius), or 3) you get objective symptoms in addition to the noise.
As to number 2, when the MIL comes on, the ECU will store codes that the maintenance guys can download by plugging into your diagnostic port (located just behind the dash in front of your right knee). The codes are great truth-tellers -- if you actually get one... As to the last, if you get other symptoms, describe them carefully to the tech and maybe that will help solve the problem.
Good luck with this.
