If the error correction algorithm can correct for the scratches then there is no sonic degradation. If the scratches take out too much information for proper correction, then you get gaps or blank spots and possible skipping. Sometimes CD-Rs go bad and develop static-like sound on certain parts or just short gaps. Unless the scratches are pretty bad though, the error correction algorithm seems to work wonders. I've got a couple of really scratched CDs that seem to play just fine.Also, if you happen to get a bad scratch on a CD that causes a glitch, sometimes it is possible to buff it out so the CD plays normally again. There are CD repair kits that contain a polishing compound to remove scratches.
