Cabin Noise (1 Viewer)

What is the consensus on where the bulk of your cabin noise originates (engine / firewall, transmission, wind, exhaust note, etc.)? ** These 2 readings are at 100kph

Probably my 13 year old mud tires

Firewall/engine for me. Unless my wife comes 4WDing, then it’s the passenger seat.

I didn’t think to add that one to the list of possible sources.

I redid my floors with Second Skin Audio Damplifier Pro and then rolled some Spectrum Sludge on top. I only did it where the original factory sound deadener was located. I also did the doors but, again, not 100%. I noticed considerable noise reduction with those two areas alone. I later installed a new headliner and used the same product under the headliner. I noticed some sound reduction with that installation but not nearly as much as the previous areas. I haven't messed with the firewall - of course mine isn't a loud, smelly diesel.

I thought Cabin Noise was one of the reasons we bought 70s.

I don’t even give it a thought as it’s 100x quieter than the soft top Defender I had!

I go with the mud tires also.

If you want drivetrain noise, get a 55.

With all of the variables, it might be cheaper in the long run to simply wear a noise-cancelling headset.

I didn't notice any difference doing the sound deadening on my Ute. Used the good stuff too. Floor, bottom half of firewall, back wall. I think my drivers door is tweeked and adding to the noise.

I didn’t run a dB meter but here was last night, 55mph, dirt road with a soft top during a thunderstorm….The click sound is the keys chain tapping if that gives you any idea of cabin noise.

We need someone to test one of those fancy Land Cruisers (aka 200 or 250 Series) to get an accurate picture of how noisy our 70 Series really are.

I can't hear any thunderstorm...
BTW, Is the meter backlight original or did you do some upgrade to it? It seems to be bright compared to mine, but maybe I should check it when it's really dark.

It was a crazy light show. Not much thunder but crazy lightning.

Original lights in the meter. It really only looks like that when dark. Hard to see otherwise.
