When scuba diving in the ocean waters, you might want to make sure your underwater radio isn't playing AC/DC music lest you attract some unwanted predators. Apparently a recent not-so-scientific study by a South Australian tour operator Matt Waller has revealed by trial and error that the great white shark is quite fond of AC/DC's lower frequency rock sound, especially "Shook Me All Night Long" and "If You Want Blood." No doubt the great whites are quite interested in blood so the song definitely fits!

According to the news agency <a href="http://www.adelaidenow.com.au/shark-tours-put-ac-in-deep-sea/story-e6frea6u-1226066785052">Adelaide Now</a>, " Mr. Waller discovered the unusual attraction for sharks when taking tourists out on his swim with great white sharks trips.  'We know the AC/DC music works best by trial and error, and we are doing more research to see what works best with different species of shark,' he says."

During Matt Waller's research he discovered that sharks actually hear better at lower frequencies, usually between 20-1,000 hertz. That is seriously low when compared with humans and man's best friend. In comparison, humans are able to hear 20-20,000 hertz, while your family dog, depending on the breed, is able to hear from 40-60,000 hertz.
