Jeff Bizub Uses Music Theory to Fix GE Engines

Talk about heavy metal. As you may have readGE Engi­neer Jeff Bizub made small pock­ets of audio and engi­neer­ing geeks giddy ear­lier this year when, essen­tially, he trans­posed the fre­quen­cies of spark igni­tion engines to pre-diagnose break­downs before they happened.

Chalk it up to Jeff Bizub’s aca­d­e­mic back­ground in music the­ory, which in all like­li­hood led him to con­sider trans­pos­ing those engine sounds into music. Engines like those pic­tured above, a Wauke­sha 275GL* gas engine, were the big breed of rum­blers the GE whiz needed to son­i­cally dis­sect. At 66,000 pounds, the Wauke­sha could power a small power plant, though in prin­ci­pal it oper­ates no dif­fer­ent than a typ­i­cal automobile.

The util­ity of this con­cept, which Bizub designed into soft­ware that could auto­mat­i­cally score the tell­tale sounds, lies in the fact that most of the knock­ing fre­quen­cies por­tend­ing a gas explo­sion and engine dam­age are inaudi­ble to the human ear. Once the job was done and the soft­ware was ready, Bizub went the extra mile and turned those knock­ing fre­quen­cies into an orig­i­nal com­po­si­tion. Check out the score, and give it a lis­ten down at the bot­tom of this post.
