the Truth is stranger than fiction
AVL Designs, an acoustical consultancy and designer of Audio, Video and Lighting systems, was never intended to be the Ghostbuster or chase "phenomena" of unusual kinds. Alas, numerous requests have been made for our acoustical research skills to be applied to haunting hums, tones, screeches, and in one case - ghosts frying chicken in an attic while singing. You really can't make this stuff up. We found no ghosts. The chicken was seasoned perfectly, however.
The video on this page is full of truth. Real occurrences. Real expertise and research applied. And, real STC data about acoustical deadening ("sound proofing").
Below, find real articles and videos about Kokomo Indiana and the the famous "Kokomo Hum". Do your own research, protect yourself if you must. Just know, Kokomo IN is NOT your Beachboys' paradise - no palm trees, no sand. Just waves... a hum, that may vex you to the core... Or you might not hear it at all... Oh, and it's also home to the world's largest cow (which may be tied to alien activity... just sayin').
Important Reference Material
The world's largest steer was from Kokomo.
Mad cows and hums run concurrently in this paired article. Are aliens baking cow genes and growing super cows on earth? We won't likely know for decades. When the cow pictured here was alive it was well before mass documentation of audio phenomena was likely, and measurement would have been impossible.
