Guest guest Posted December 13, 2004 Report Share Posted December 13, 2004 http://www.unknowncountry.com/news/?id=3155 Kokomo Hum Identified The source of the highly annoying Kokomo, Indiana hum, that has been making some people sick since 1999, has now been identified. An acoustics consulting firm says two industrial fans are sources of a mysterious sound. Jim Cowan of Acentech, in Cambridge, Massachusetts, was hired by the town to make a 10-month study of the hum. He finally traced it to low-frequency and infrasonic tones coming from local industries, and narrowed it down to a cooling tower fan on the roof of Kokomo's DaimlerChrysler Casting Plant and an air compressor fan at Haynes International. Both companies have agreed to silence their fans. Haynes International has installed a muffler, and DaimlerChrysler is working on the problem. The hum did not exceed 60 decibels, and sound researchers say negative health effects from low-frequency sounds start at 90 decibels. But residents who reported sleeplessness, chronic fatigue, headaches and nausea blamed it on the hum. Cowan says, " None of these people are crazy. Nothing is being made up. " Looking for peace? First you need perfect alignment.
