Is there really a huge difference between 58 & 68 db?

Yes. Every 3db is a doubling of acoustic energy output, IIRC. 10db increase will sound twice as loud. It's been a while since I studied this stuff, but I think this is accurate.

Yes that scale is logarithmic. So going up by 10 is 10 times louder (every 3 db is a doubling of the level). I have read that the human ear does not work linearly so for our hearing a 10 db change will sound twice as loud ( not sure if this is 100% accurate)

Every three decibels is roughly twice as loud. I would say there is a significant difference between 58 and 68 dB. 58 dB is like a Honda inverter and 68 dB is an open frame contractor generator

I've seen 68db gens advertised as good for RV and camping for half the price

Unless you are boondocking, the quieter the better. In most campgrounds, if the Ranger/manager thinks it is too loud or gets complaints, you will be prohibited from using it or strictly limited as to when. If you try to run a construction generator in a campground you will not be welcome.

Here are some 'common' DB levels to compare...

50 refrigerator
50 – 60 electric toothbrush
50 – 75 washing machine
50 – 75 air conditioner
50 – 80 electric shaver
55 coffee percolator
55 – 70 dishwasher
60 sewing machine
60 – 85 vacuum cleaner
60 – 95 hair dryer
65 – 80 alarm clock
70 TV audio
70 – 80 coffee grinder
70 – 95 garbage disposal
75 – 85 flush toilet
80 pop-up toaster
80 doorbell
80 ringing telephone
80 whistling kettle
80 – 90 food mixer or processor
80 – 90 blender
80 – 95 garbage disposal
110 baby crying
110 squeaky toy held close to the ear


EDIT... just remember, some of the louder ones are momentary.
Imagine how annoying they'd be if constant . (such as a running generator)
