RV AC too loud? Worth it to Insulate?

- To my surprise insulating the AC of our travel trailer it did not dramatically change the decibels, but it did make the sounds and tone of the AC quieter. The decibels went down from 75 to 70. I did measure the decibels by using and app, but any difference is worth it. It cost me around $20 and 30 minutes of my time to do. So was it worth it? Yes, 100%.

The reason you don’t see much of a change in the meter readings is because decibels is a logarithmic scale rather than linear. That means a double in the decibels does not equate to a double in loudness - it is way more. For example, a 60 decibels sound is 10 times louder than one at 50 decibels, and 100 times louder than a sound at 40 decibels.
I really appreciate it! This is a very important point because it really did change a lot, just not that I could show in numbers. Thanks!
I did this mod and noticed it was a lot quieter. I didn't test the decibel level, but there is a noticeable difference in the volume. It's not silent, but now we can sleep with the AC on, without ear plugs, and keep the volume of the TV lower. Only took about an hour of my time and very inexpensive materials.
That is awesome!
Soft starts are a pretty big help also.
I can hear the tone change. Does seem worth a go! Thanks
Of course! This is one of the most common complaints regarding AC units (other than cooling!) So its nice to have a fix for it.
Missed the chance to mod the air flow better
Do u recommend it or not
@@Dr1Salman yes I do for the amount of work and the price of materials. It’s truly worth it.
we have a very similar ac unit. i was wondering if there was any way to divert the air into more than 2 directions. in ours the vents direct to opposite ends of the rv and none to the sides which is where one of our slide outs is (kitchen table). in the middle of summer this area gets really hot. i tried putting cardboard from vent taped to ceiling to help divert air to table area but it was a flop.
Sadly there isn't a solution or product on the market that I know of that can be of assistance. I could get extra fans to cool the trailer down as much as possible. Unfortunately, these RV AC units can only cool down the camper 20 degrees lower than the outside temperature.
A little late to reply, but check out this video.

This guy cut a steerable vent into his Coleman Mach.
When we insulated ours we noticed most of the sound came from the flexible cold air tube blowing out. I think the reason why this guy's unit ended up being loud with the vent, is that the vent lines up with that cold air duct.
If he'd put the vent where the manual controls are instead, I think the insulation would have absorbed a lot more of that noise.
