The City of Kokomo hired Acentech to investigate the “Kokomo Hum”, a mysterious sound source allegedly causing illnesses for more than 100 people among the 47,000 residents of this central Indiana city. Our mission was to find the source or sources of this noise. In that regard, we interviewed the affected residents, monitored sound and vibration levels at representative homes around the city (in the presence of residents to tell us what they were experiencing), and identified specific pieces of equipment in industrial facilities that were emitting potentially offensive low frequency tones.

In addition to acoustics, this project involved extensive public involvement. As this project had international exposure, Acentech also dealt extensively with the press.
