If your windows rattled a bit on Monday night, we can tell you why.
The Royal Regiment of Canadian Artillery School held some live-firing training in the Base Gagetown training area.
Capt. Michael MacNeill, public relations officer with the Combat Training Centre, noted cloud cover can increase the intensity of noise.
“As one of the largest bases in Canada, various forms of nighttime training are very common at 5th Canadian Division Support Base Gagetown, including live-firing activities. It also is important to note that cloud cover is a factor that may increase the intensity of noise. While sound waves spread into the atmosphere and eventually disperse on a clear day, cloud cover can redirect sound waves back towards the ground and therefore result in a potential increase in noise level,” MacNeill said.
People on the Kingston Peninsula and Darlings Island heard the rumbles on Monday night.
Some communities will hear the noise again on Wednesday.
Artillery fire may be heard near Browns Flat, Johnson Croft, Lynch Corner, Browns Corner, Glenwood, Central Greenwich, Welsford, Nerepis and Oak Point between 7 a.m. and 8 p.m. as training continues.
The training allows the Royal Regiment of Canadian Artillery School to practice advanced skills, tactics and procedures.
