What fall out when you decamp a rock across a rooted lake ? If a video that is developing plenty of interest right now is right , you get a noise that sound like something out of a scientific discipline fiction film or a Pink Floyd outtake .
Most of us have tried to skip stone across ponds , and some have even managed to make the pebble skip several times across the water . Only those populate at gamy latitude get to try the same affair on frozen lake . So when Cory Williams , who exists on-line asDudeLikeHella , found a fixed lake in Alaska , he was reasonably worked up . Well , very excited . But not as emotional as he became when he heard the sound the stones make . The interesting material starts at around the 4.00 stigma .
Understandably , some citizenry wonder if the phone was real , or if Williams had add it in later . After all , if this is the sound the stones always make on frozen lakes , how come everyone living in colder latitudes do n’t hear it every winter ? slew of dweller of higher latitudes have support hearing these sound before . According to Canadian websiteCottage Life , “ Underneath the crank the piddle is n’t whole . Ice vibrates up and down , similar to a drumhead or cymbal vibrating after being struck . ”
The resound effect is a production of the dissimilar speed of audio in different spiritualist . The speed of auditory sensation in air is 343 m / s ( at 20 ° blow ) , but this rises to around 1,400 m / s in water andmore than 3,000 metre / s in ice , although even the lattercan vary . Sound wafture that make part of the journeying to our ears through ice reach us before those that come directly . To refine things a little further , the “ upper of auditory sensation ” canvary with frequency . In melodic line this effect is small , but in water ice it can be substantial , a phenomenon audio creative person Andreas Bick has usedto singular effect .
Not everyone who has tried skipping Harlan Fiske Stone on ice has had the same experience because , as Cottage Life observe , it also depends on how the ice was take shape .
“ dissimilar ice-skating rink get different sounds : A high - pitch noise when your rock hits the lake in all likelihood means you have ' clean ' trash . This is the glassy , see - through ice that ’s formed under dusty , still , non - snowy status . ' C ' methamphetamine hydrochloride — the unintelligible ice that form after snow falls on the surface of the lake , becomes saturated with piddle , and then freezes — produces a lower - frequency sound , because o.k. grains in the ice absorb some of the noise . ”
