Hawaii Game Management Advisory Commission Meeting Minutes – January 17, 2017 the noise floor. Our study showed that – I’ll bring Puuanahulu into it – the third sound study we did – they actually mapped the island area and did contours, you know, the topography – how sound would propagate down there. We did sound tests, we brought up Richard and I had our guns up there, ah, they, they, they measured us at 180, 360, 90, 270 angles to get different sound levels. They also spent a week or two – I don’t remember exactly – down in the quietest areas of the Waikoloa Village – some of the court yards that are sheltered from all the highway noise – from all the everything else that – if you’re gonna hear something that’s where, that’s where it would stand out the most and they did they, they recorded sound down there over a period of time and then they mapped it, modeled it, so they could show that with only one exception our sound levels from the rifle fire and from the shotgun were below the ambient noise level at those quietest areas. The one exception was when we had the shotguns aimed towards – or would have had those shotguns aimed towards the resort in that circle that we talked about earlier? That would have carried enough sound forward that they would be able to hear that so – and all we would have to do to resolve that is turn the direction of fire 180 degrees around. TL: Shooting into – is that a fair enough sound abatement type and all that for the arrangement that they had there? JO: It helped attenuate it and foliage around there, certainly, helped as well – it’s not as good as people might think and obviously that neighbor heard it enough and I’m not saying that it was loud where she heard it – but it was, it was discernable and that’s all it took to generate a phone call to the authorities. TL: One of the other questions that we’ve had and one of the reasons why we’ve asked James Cogswell up here is if there are areas, I mean, if, topographically what would be the ideal? JO: Flat is ideal for managing your land – you want a flat area where, you know, all the shot fall, you know, all your bullets are expended into the ground, sandy, alkaline base soil material is best for that and it just simplifies the process of recovering the lead. TL: A canyon or something like that would be? JO: What’s that? TL: A canyon or something like that wouldn’t... JO: If the flow is flat and you had proper berms – now one of the things that a lot ranges have gone to and you can look this up on line is they’ve gone to Geo Sel – sidewalls and backstops – berms – and these are fabric 25
