Sharks fanateyut from music
The shark is a predatory inhabitant of the deep sea. From one only its fin in his veins the blood run cold. But the thrill does not like to tickle nerves, looking danger straight in the eye. It is for these thrill-seekers tour operators have specially arranged meetings with the sharks. Here only the predators don’t always show interest in sitting in a cage to the audience. But the money paid, and so wayward sharks need to attract by any means. Traditionally used for this purpose the bait out of the fish slime. But the Australian tour operator Matt Waller has found a bloodless alternative to attract sharks, better working fish decoys – hard rock performed by the legendary band of the 80’s AC/DC! Looks like reckless Australian rockers, who have sold over 200 million albums worldwide, there are new fans – great white sharks. Solid!
Several times a week, the company Waller of Adventure Bay offers cruises to the Bay of sharks Natanovich on the Islands South of port Lincoln. Here face to face you can meet the largest predatory fish on the planet – great white sharks who hunt in these places on the seals. Taste in music from Queens of the seas fully meet their bloody reputation. In special favor with the sharks turned out to be two of the hit rock songs: “If You Want Blood” (post) and “You Shook Me All Night Long”.
Waller himself was not an expert in the field of shark physiology, but he suggests that, most likely, the secret of success of songs in such an unusual audience lies in their low frequency sound. He watched as sharks, hearing favorite songs, swim, and begin to RUB the noses of the cell, whence emanate the sounds, as if trying to feel the music.
Sharks have no ears, but they have internal ear, and they are able to perceive sound vibrations and through the upper part of the skull. Research scientists Donald Nelson and Arthur Murberg showed that the ears of sharks are able to perceive vibrations from 10 to 800 Hz, but the greatest interest they show irregular pulse fluctuations of low frequency in the range of 375 Hz. Wondering what the best hearing among sharks, according to ichthyologists, it is the great white. Now it turns out that they have even their musical preferences .
To pay attention to music by Matt Waller made a practice of some companies to use sounds of a certain frequency to repel sharks. Really, why can’t there be a reverse? In addition, the use of music to attract the sharks is not so unique, because it resonates with the practice of the native inhabitants of Pacific Islands, attracting sharks, rattling under water coconut shell.
Waller is not going to rest on our laurels, and plans to continue his field studies of the music preferences of marine predators. On turn new shark species and frequency analysis of the beloved “fish” songs to identify their common acoustic characteristics.
Well, as they say, on taste and color of comrades not, but still check out the tastes of great white sharks offered by the legendary audition “You Shook Me All Night Long” performed by AC/DC. Who knows, maybe you have something in common with sharks?!
