WATERLOO - A Waterloo man upset by a neighbor's loud music took matters into his own hands.

Carl Herold, 62, said he was tired of constantly calling police to complain about the "hippie tunes" coming from across the street, so Wednesday he got an air horn.

"I just started blasting it," said Herold, a resident of the Chautauqua Park neighborhood, which is across Conger Street from Exchange Park.

Herold's cacophony caused Waterloo police to arrest him for disorderly conduct and seize his air horn.

Herold said he's had a long-standing problem with the music and has filed complaints about the neighbor allegedly building a shed on adjacent city property.

"I don't have to sit in my house and hear his music," Herold said. "We called a number of times, and nothing seems to be done."

He's also upset about residents who park on the sidewalk.

The problems came to a head earlier this week, and Herold bought an air horn that was taken from an old dump truck.

He set up the horn on his deck facing the neighbor's home. He ran a hose to an air compressor to power the horn. Another line led to his living room where he could control the contraption from his couch.
