What is your typical noise level?

3db and under is usual in my area. Mostly it's atmospheric hiss. Some days I can turn on the preamp and ramp up the rf gain, and it's still quiet. Other days no preamp and rf gain turned down because of the static.
Sirio GPE 27 5/8 wave on the chimney.

Sigma venom 5/8 wave. 27' To the bottom, 4' ground rod. I have my antenna mast, metal trailer house siding and all of my radio equipment rf bonded with flat tinned copper braid.
I have zeoro noise. I dont run anl and talk to a barefoot station 40 miles away every morning.

Here of the day on 40m it's a S2, then of the evenings it runs up to a S7 or so...
80m thru 160m it runs pretty much a S9 for the most of the time, really sux but what can u do ...

Even with all power off in my house I have a solid S5-S7 with both the President Lincoln II + V4 and the Anytone AT-5555N II on a Maco V58 antenna. I'm not near any above ground power lines and live out in the sticks a bit. I'm just thinking back to when I was a kid in the late 1970s and I could hear local folks a long ways away (40-50 miles some times) because the noise level was 0.0. They would not even move the needle but I could just barely make out their voice. Maybe the radios were just a lot less sensitive then too.
cept when 1 of the wind towers screw up,its so quiet you have to look at radio to see if its on. both my lincoln vii+ and galaxy 99v. either sirio 2008 or a 99 dont matter
If you are using a switching power supply that may be the source of your noise. I had to add some ferrite chokes to mine as it was giving me an s3 of switching noise.
haha at our christmas party our radio club gift i got was a huge bag full o ferrite beads all sizes. might need em some day.
only time i hear noise beside windtowers is a car with bad ignition going by buzzing into my radio

very good gift. I just orderd a bunch of type 43 ferrite toroids to filter out noise on our first 2 pill 2879c base box. The thing walks the dog it is ab biased and low pass filtered doing about 200 swinging 600 peak. but the two switchers inside are too noisy so common mode filter it is.
When I had the main breaker for the house turned off a few weeks ago, I hooked the radio up to a spare 12 volt battery I had in the garage and had the same general level of noise as with the house power on.
I've decided this noise is just a byproduct of the modern world, one of many things that are no longer as they were in 1978. I can't control it so I will just enjoy what I can hear above that base noise level. I did notice it is getting down to S3 at times on both my President Lincoln II + and Anytone AT-5555N II so that's progress.
