Last month I had the windshied replaced on my wife's Bonneville and I asked about the Camry's "sound absorbing windshield. He said he had not replaced any on a new Camry but he had replaced one on an Avalon Limited. He said that the plastic layer (laminated between the two glass layers that makes the windshield shatter into little pieces) was a bit thicker and did cost about 20% more. This was at a Guardian Glass shop. They used "Guardian Glass" on the Bonneville, but I don't know what glass they used on the Avalon - mfg. glass or their own (I'm guessing it was their own brand.)
