Sleeper Cab Vibration Noise?

The noises from vibrations, such as reefers, are much louder in my sleeper. Sometimes I'll barely be able to hear anything in the driver's seat when I park then all the ambient noises become a lot more audible once I sit down in the sleeper bed. Foam ear plugs don't help with the low pitched vibration noises. Does anyone else experience this or know what causes it?

I just have my own truck's vibrations and noises to deal with. I have never had a problem sleeping. I do love the quiet of sleeping with the truck off in the cold weather.

I love the sound of the truck idling, puts me right to sleep. I'll frequently park right next to a reefer.

But, some frequencies will cause ungodly vibrations when a couple trucks are parked together. Rattles caused by vibrations drive me nuts. Usually if I can when that occurs, I'll move to another spot, if I can't then I'll up the idle on my truck for a bit to get the frequencies to change. Other times just bear with it.

Yeah, man. The steady hum of an idling truck is very relaxing. An annoying, intermittent Bzzzz! Is like nails on a chalkboard.

Just as bad, in my opinion, is a truck that steadily loses air such that the governor cut off goes Ssspttt! every 30 seconds non-stop🤬

Yes, most trucks idling are like a white noise and I can go to sleep with that. My truck idling or noise canceling earbuds blasting white noise are the only thing that will cancel out refer noise for me. I avoid parking next to them like they're the plague. The refers hauling frozen freight are the worst and some of them sound like jackhammers. I could be dead tired and still not be able to fall asleep next to one of those.

I find it harder to sleep when my reefer is off, which makes no sense at all. But considering my company hauls 90% reefer loads, I guess it's just normal for me.

When I go to sleep I don't idle at all. Don't like the vibration from the truck. Love my APU

Reefer:

A refrigerated trailer.

APU:

Auxiliary Power Unit

On tractor trailers, and APU is a small diesel engine that powers a heat and air conditioning unit while charging the truck's main batteries at the same time. This allows the driver to remain comfortable in the cab and have access to electric power without running the main truck engine.

Having an APU helps save money in fuel costs and saves wear and tear on the main engine, though they tend to be expensive to install and maintain. Therefore only a very small percentage of the trucks on the road today come equipped with an APU.
