I've got an unused Model Y Cargo Cover. I really don't like it, and the amount of noise it blocks is not worth the inconvenience of it existing and being in my way. I did some decibel meter noise tests with and without. On my local very bumpy street during a 2 mile test, I averaged 65.7 decibels with and without the partition, but peaked 4 decibels higher at 84db without the partition vs 80db with. I did a similar freeway test and had an average of 72.3db without the cover, and 72.1db with. It peaked at 78.9db without the cover and 77.6db with.
