We have noticed the presence of a new loud noise in
Decatur. ,,,Just east of Sycamore and Church on the north side of Sycamore is a fenced area (perhaps 10' x 30') from which a loud continuous noise is being emittedl. It sounds somewhat like a large industrial fan. When walking by on the sidewalk in front of it, I get a sound level of approx 80 dB, well above noise ordinance limits.

Please advise .
