What?

I was listening to a radio ad this morning for a hearing aid product. Now, as funny as that is all by itself (trying to sell a product for the hard of hearing using an advertising medium that only makes use of hearing), it gets better. The shtick of the ad was that even with your stereo cranked, you can't quite hear the rock music to the same degree as you used to when you were younger. Buy this hearing aid so that you can hear that wonderful rock music blaring just like it used to.

Awesome. That blaring rock music which likely contributed to your current hearing loss is now going to be amplitudinally [my word - don't even bother looking it up] enhanced even more by an amplifier plugged right into your damaged ear. Great idea.
