Jeff Bizbub spend his solar day as a GE locomotive engineer , but he also has a degree in music theory . And that works just hunky-dory for him , because he ’s been able-bodied to use his aesthetic know - how to troubleshoot trouble in machine .
The firing spark engines he work with are very large — they’re nearly 11 inches around and they produce 4,800 horsepower . But they ’re so big that gas is sometimes ignited along their walls rather than at the center where the sparkplug is . If that materialise , flames nada around the machine , crashing into each other and make the walls vibrate , producing a hallmark knocking sound , which can severely harm the engine .
So to fix the problem , Jeff put his musically - train ear to work .. He toldGE Reports :
“ I put my auricle against the cylinder and could pick up even with earmuffs on the multiple frequencies inside , ” he says . “ I acknowledge that there was a halfway oftenness link up to dullard size , but as with any instrument you ’ll have multiple vibrations that will occur . ”
He got his hands on a 16 - channel digital recorder , a retinue of music software to monitor the absolute frequency of the noise , and a 64 - band equaliser to cut across the spectrum and frequence of all that rachet . Along with a squad of research worker , he wrote some industrial programs and algorithms to analyze the engines . Now his mill uses all these tools to identify problems in each and every machine . There was a merriment by - mathematical product , too — Jeff made these sound into a series compositions , one of which you may hear in the above clip . [ GE Reports ]
