Miscue Laneous

What is the question to which the answer is "9W"?  Answer at end of entry.

Loaned my Bose noise-canceling headphones to the missus for her recent sortie into Chi Booma Gow Gow, and she loved 'em.  This week on our See Arizona tour (985 miles in three days, all in-state) told her of a review I'd read on the Honda Odyssey, a truly marvelous van.  Told her that in this van, whether the radio is on or off, it's putting out the same noise-damping technology as the Bose 'phones, making for a sepulchral sound level.  Always thoughtful and on the lookout for health and safety, she rejoins, "But doesn't that cause cancer?"
