Tearing tape off the roll can be a satisfying way to entertain yourself in the office . But you ’re not just wasting office supplies — according to young scientific studies , that taping is also let out X - rays and ultrasonic sounds .
Though you might not think this from experience , peeling adhesive material is actually a version of fracturing . It ’s a physical process that ’s related to more obvious types of fracturing like cracking a careen open . consider in this way , it becomes a number more believable that flake mag tape expiration X - ray . After all , a fragment rock’n’roll can sometimes release Muriel Spark .
A few years ago , researchers discovered the ten - irradiation emitted by unclothe adhesive taping in vacuum , by recording the process in the research lab . you may see what they found in this video .
Today in Nature , another squad of scientist reveal that the “ screeching ” sound of tape measure desquamation is in reality quite complex . Much of the sound is in the above - hearable range of mountains for man . I have sex this representative of how they staged the experiment , to record tape rip .
indite the investigator :
We look into the genesis of the screeching sound commonly heard during tape recording peeling using synchronised high - speed video and audio acquisition . We determine the peak frequency in the audio frequency spectrum and , in addition to a peak absolute frequency at the upper closing of the hearable range ( around 20 kHz ) , we find an unexpected strong audio with a high - frequence far above the audible range , typically around 50 kHz . Using the corresponding video data point , the stock of the key frequencies are confirm as being due to the infrastructure “ fracture ” bands , which we herein keep an eye on in both high - speed continuous undress motions and in the slip phase angle for stick - slip peeling motions .
So when you ’re yank tape off the spool , you ’re actually throw off highly energetic particles and ultrasonic noise . The whole process wander up being about as violent as it sounds .
