From the patch notes:
"The “Replica Rithana-di-Renada” collectible furnishing can now be toggled on and off, if for some reason you don’t want to listen to ancient Khajiit chants 24/7."
My khajit has this in her bedroom and now can sleep without going insane!!
I just noticed tonight when she got in there that it can be toggled. I'll have to read the rest of the patch notes. Excellent!!
