REPORTING · 30th June 2014
Councillor Phil Germuth moved that $17,800 be allocated for the sound proofing of the Fire Mountain Shooting Range at the Regular Meeting of Council on Monday, June 16th in the 2015 municipal budget.
Councillor Mary Murphy wanted to know if it would be effective. She was told the only way they could control the noise is to insulate the metal structure. The only other option was to build a sound barrier around the facility which they believe would be impractical.
A report to Council gave several options. The first was $15,000 for sound absorbing material, the second: $17,500 for spray foam and the third option, $27,000 for Thermafibre installation. The first option was dismissed out of concern of vandalism and limited success in outdoor ranges. The effectiveness of the second option could not be gauged so it was dismissed by both parties.
It was suggested that using the Thermafibre on the roof of the shooting range would reduce the noise. This would also reduce the cost to $17,800. This was the recommendation to Council. If the Thermafibre proves not to be significant enough, they could finish the rest of the building for $9,800.
“The Thermafibre installation, I see that as the best way to go from the choices that were there. A lot of the noises you get is because it’s a sheet metal building. The air reverberates in there and then goes out. This insulation is designed to encapsulate it in there and absorb it so it doesn’t get out,” said Germuth.
He suggested putting the extra costs off to a future budget.
Murphy could not see how it would take care of the problem unless the building was completely sound proofed. She was told there was no way to stop a gunshot sound further down the range once the shot has escaped the building.
However, Martin Gould, Director of Leisure Services told her a large amount of noise, according to the RCMP guide and regulations, the noise inside a metal structure is the reverberation of a building. The gunshot is the initial noise which echoes, the metal building makes it echo a lot and then the noise escapes as well. He said the only way to stop the gunshot noise was to stop the shooting.
Feldhoff asked if there was any engineering that told them how the gunshot noise would be reduced by the time it reaches Cablecar. He was told by Gould he hoped the noise reduction would be significant and there was insulation installed in a shooting range in Vancouver and it experienced up to 75% noise reduction.
The motion was called and carried.
