Dear oh dear, how can you write such blatantly incorrect statements? Just think about the various devices fitted to a roadworthy car. You might recall that one of these devices is called a horn, which is (believe it or not) an audible warning device. That means that it is a warning device that relies on the auditory system of it's intended recipients. It's designed for people to hear it.
Now, (think carefully before answering this one,) which came first, the horn or the massive stereo pumping out drum and bass?
Sorry, but you deserve a lot of
