Decibel Measures
Decibel Measures
Just wondered,
I replaced the rubber weather stripping on my 1997 Discovery LSE. This included all of the doors. On the back door I added more weather stripping across the top of the door frame to tighten everything up.
Driving at 55 on flat ground at speed my decibel measure is at 61-63 one foot above the transmission shifter in the center. On a hill it increases to around 71. How does this measure up to you all?
Thanks for any feedback.

what are you using to measure decibels? I dont readily keep equipment like that in the truck. My truck sounds like a single prop airplane because of my tires. I think it shook a filling out of one of my cavities once, so im assuming if more decibels is better, then i might have the high score.

I'll bring one home from my office and experiment, may take a couple of days to get results back to you.
Meanwhile, if sound level increases 10 dB going up hill, when is last time you greased drive shafts (front and rear), drained and refilled diffs and transfer case, what oil weight and type are you running in them, and when was tranmision fluid /filter changed? Exhaust leak? Just thinking about what could make that much of an increase...
I went to 85W140 synthetic in my transfer case and I think it is quieter, but that is based on the old Mark 1 Ear Drum, which has been abused in my distant youth by Iron Butterfly and such and obnoxious volume levels... point being that hearing damage is forever.
