Sound- absorption or reflection

[Al Scudder]

I havw ONAN RS12000(12K)unit outside my bedroom window (10 Ft) and can not hear it when it is running. Insulation is a 1" thick sponge with reflecting face sheet that is lined inside of the box that the generator
sits in. Works well cant tell you how many times I have awaken in the morning to find that the power was off for 6 hours or so

I would assume that the sound deading material used in these generator compartments actually reflect the nooise down. so the noie is forced under the coaches. Many boats and I belive that some new coaches now have a box lined with sound deading which the generator is placed. just a thought jim riordan 88 wbwl xxv stuart fl --- On Fri, 2/20/09, Ernest Ekberg com> wrote: From: Ernest Ekberg com> Subject: [WanderlodgeForum] Sound- absorption or reflection To: WanderlodgeForum@yahoogroups.com Date: Friday, February 20, 2009, 7:43 PM After installing many generator compartments with the new insulation, I was wondering if there is a manufacturer that offers both. I insulated Bob Lawrences' generator compartment last December. He measured the db levels before and after and found that while the heat was reflected from the interior of the coach, the sound was also deflected to the outside. thus his db levels INCREASED to over 90. I know my with my coach, that I have been asked to park way downwind as my generator is really loud. Maybe its the dogs I carry with me??? But, if there is a product that will absorb that sound while reflecting the heat, let's talk about it. Ernie-83PT40 in Texas, buying earplugs by the case~
