The Arkansas National Guard issued a noise level warning for a North Little Rock neighborhood Thursday, 24 hours before firing a 105 millimeter Howitzer, an artillery weapon that causes loud booms and ground vibrations.
Maj. W.B. Phillips II, state public affairs officer for the Arkansas National Guard, said guardsmen will fire blanks between 1 and 3 p.m. today and again between 7 and 10 a.m. Saturday as part of a troop review and rehearsal.
According to the Journal of the Acoustical Society of America, a 105mm Howitzer can produce 171 decibel blasts, more than 25 times louder than an average rock concert. A jet engine takeoff is normally about 150 decibels.
Phillips said the Amboy neighborhood of North Little Rock would experience some loud noises and ground vibrations, as will other people near the southeast portion of Camp Robinson.
"We're all pretty used to it; nobody that I know of has ever complained," said Angelica Barnard, president of the Amboy Neighborhood Association. "When you live next to a base like that, you can't get away from it.
"You can't move next to an airport and complain about the planes," she said.
Barnard said the Amboy area often hears artillery fire from Camp Robinson and that the Arkansas National Guard reliably posts the noise warnings on Facebook before such blasts.
North Little Rock Police Department spokesman Sgt. Amy Cooper said dispatchers were notified of the artillery fire in case residents didn't know where the noise was coming from and called 911.
