MILWAUKEE - You don't have to attend the big bash to hear the big roar of Harley-Davidson engines. With tens of thousands of motorcycles expected to roll through town, that roar will reverberate across the city.
But getting too close can be a little dangerous.
TODAY'S TMJ4 invited a sound expert to track the volume of this weekend's 110th anniversary bash.
"They compare to that of 18-wheelers, and some are even louder," explains Dr. Stacy Ryan, an audiologist at UW Milwaukee. "It's dangerously loud even under 30 seconds of exposure. Riders should consider wearing ear protection."
Ryan brought along her decibel meter to the party, and measured one Harley's levels at more than 120 decibels - the same rate as a jackhammer.
But not everyone likens it to noise - Harley riders we spoke with refer to a Harley's engine as music to their ears.
"I guess you can say it's a Harley-Davidson symphony," commented Darryl Meeks, who rode in from Oshkosh. "There's a nostalgia to it and I get goosebumps."
