Ducted Air Conditioning; Sound Level Nnumbers

Directly under the main a/c vent and in front of stove: 84-85 db. Sitting on the bed: 65 db. So, as would be expected, the sound level drops inversely by the square of the distance (if you could hear that accurately). Note that reducing the fan speed lowers the 6' reading to 59db; significant but not quiet nor sufficient flow to keep us cool (75) when the outside temps climb in bright sunshine.

For comparison ... Normal conversation at 3'= 60-65dB

City Traffic (inside car) = 85dB



As promised ... we finally took a break from enjoying / playing in our EB w/ ducted air to get the

following ducted air conditioning sound level background readings;

* fan on high, compressor running *



Seated at the cushion juncture: 54-55 db; down from 63 db / 59 with fan on low; reduction of 8-9 db.

In front of stove directly under inlet for ducted air: 60 db; down from 84-85 db; reduction of 24-25 db !!!

Sitting on the front bed: 54-55 db; down from 65 db; reduction of 10-11 db.


Even by this unscientific means, those difference numbers are significant and dramatic for sound reduction.

The ducted air is also very effective in cooling both ends of the trailer.



It is really now quite amazing that we can be sitting in cool comfort and listen to Pandora or a movie at the same time as the AC is on with the fan on high. I can now talk to my wife when she is in the galley area under the ducted air intakes and not even need to raise my voice to communicate . It eliminates the stress of the loud A/C background noise when inside the AS trying to do much of anything other than sleep... we spent much of last weekend just sitting inside of the Eddie Bauer listening to the quiet while the outside temps were above 90 F. Do we like the ducted air and is it worth the depreciation on our trade in YES !!! Emphatically; however, YMMV.
