A father of three won a shouting contest with a roar louder than a passing train. “If you want a war, you go!” Yoshihiko Kato shouted. The sound meter registered 115.8 decibels, louder than the racket of a train passing overhead on an elevated railroad. For that winning shout, Kato won the $750 grand prize of the 10th annual Halls Year-End Loud Voice Contest. Kato admitted that he probably built up his loud voice shouting at his children.
