I can handle sleeping near a reefer or a loud truck.....

Man ive patched air leaks with duct tape and got better results than every 50 seconds!... Lol

 

Seems like every time I go to Jubitz there's some p.o.s. truck with an rgn type trailer from the east coast parked along the curb near the NO IDLE section with his spitter going off every 30 seconds and you NEVER see the driver NEVER.

 

Or deaf like me. No issues.

As Sgt Schultz modified. "...I hear nothing, nothing..."

However, should a sound be unnatural such as someone stepping onto my rig or the reefer coughing Im all over it.

 

Yes. The skin provides the sensory impact of sound if it gets past the airride on those trucks. And you would be surprised at how busy a big truck can be moving or sitting still. The Body is a wonderful machine, take away the ears, you get eagle eyes and a feel for the world really fast. If everything is normal no problems. But introduce something NOT normal then.. boom all awake looking for the issue.

Bridges are my weakness. We have some concrete and girder bridges here in Arkansas that fail to constantly flex and move under the heavy traffic on it. I look for that as a example through the skin.

Or a wheel starts shaking off a loose few lug nuts (Like the old spoke wheels might do) you get to feeling that through the frame to the cab and start looking for it before it escapes and really causes a problem.

 

Probably not an actual air leak just the unloader valves in the compressor itself, if they were leaking air that bad you should be able to hear it. The straight pipes just sing you to sleep at night, at least if you grew up riding around in trucks.

 

I've been operating farm equipment since I was 5, no mufflers on anything but to ride around in a truck with straight pipes all day and then go to sleep with like that you got to be
