Possible cabin noise of 100 decibels

Needed to test this with a dedicated meter but for used a Sound meter app on my Android phone to check the noise level.

60-70mph on the M25 showed 100db. Went down to 79 when traffic was at a stand still.

If it really is 100db then that's ear damaging levels.

The noise I think is wind and tyres noise not engine or exhaust.

Might need to check my door seals.

I doubt it's 100 when on the go and very much doubt 79 standing still. Unless your boot is full of amps for some serious ICE :-) If it was anywhere near 100db we would all be deaf in weeks.
Have a look here for more info. ISVR Consulting - Noise and motorcycle helmets
Gives you an idea of how loud it is on a bike, middle of the graph hits 100db at about 150kmh (90mph ish)
I'll dig out my db meter and do a proper test ... Just for fun.

No way its even close to 100db. Generally a car is rated around 80-85db in traffic and even with crap seals there's no way it should be approaching 100db.....that is motorcycle loud

*FYI: Each 10db increase is equal to approximately double the perceived "loudness"

Never believe what an uncalibrated instrument tells you!
