Sound- absorption or reflection

[Ernest Ekberg]

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.

We will look into re manufacturing or redesigning a similar product
that will work as sound absorption as well as heat dissipation
It will take some time to get a satisfactory product.

Let me know what you find Stephen. Am
about ready to rework my gen compartment.

Boeing is using a foam to insulate their new Dreamliner called
Basotect. I don't know anything about it other that it is supposed to
have high sound absorption capacity and good thermal insulation
properties.

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 wrote: From: Ernest Ekberg 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.

Hi All
Reading the info sheet on Basotect , sounds like the product were
looking for . I would like to try it .

To disipate heat, is to transfer it. Steve maybe you can disapate it
thru a dupree valve back to the tank? Call it Hot$$$$ ?

I understand that the vault gets up to +250 degrees(USA). I guess
that is a factor for Ernie to consider once he removed the disipation
path of the vault heat to the bus interior. where does that heat
now go.

Insulation keeps environments from disapating heat. heat is removed
so the method to remove the heat in the compartment would now be the
radiator system and the diesel engine is the heat sink, but the
diesel engine caused most of the heat. If the origional design was
not intended to do that it would have to be beefed up

If you insulate the exhaust the otherwise exposed metal does not
radiate heat in the compartment. heat goes out the stack with the
exhast air. But is the stack able to take all the extra heat.

If someone complains to me about the noise my genset is making I
say "What? can't hear you, my genset is too loud".

Jim, while the some of the noise was deflected down, 30 more db was reflected to the front of the radiator. Bob's coach has the front fan/radiator.
