Think of it as putting your finger on a small bell and ringing it. Much quieter right? I come by the info by knowing a bit about physics..... and being a mechanic :þ I would ASSume that by putting small dampeners there, it prevents the NVH from travelling to the body (which will amplify it) and potentially bother the driver. The other likely cause would be due to Toyota adding disc brakes to an existing twist-beam and finding squeal/groan complaints. Rather than making a new twist-beam they just bolt those dampeners on until the next redesign.

In practice removing that dampener will likely result in no noticeable change in NVH to the driver.
