What is the sound level of Your Listening Room?


I am curious about what the sound level is at your listening position with your system turned off. I have checked mine and during the day it is about 43 dB and at 1:00 a.m. it can be as low as 28. I can improve the daytime level to 35 dB by turning off the refrigerators and air conditioner. What have you done to improve the sound level of your room?

I am considering adding a listening room to the back of my garage (wife is on board because she needs more storage space) and if you have made improvements that have reduced your ambient noise, please share them.

Interesting. Everyone is so interested in environmental noise. The noise on a record might be 60 dB down if you are lucky. Now , if your turntable is not isolated you can take that environmental noise at say 80 dB down and amplify it with your turntable so it is 40 dB down. Clever. So, if you are really worried about it get a decent isolated turntable or buy yourself a MinusK platform. 
Mike all that stuff is great but it will not save you from the trucks driving down the street. It does sound like your place is out of the way. I Live on a cul-de-sac 1/2 mile from a main street. On my other side is an 18 hole golf course. So, for a house not to far from society I'm pretty quiet. But, noise is never a problem for me. Maybe I listen louder than most but for whatever reason noise is never an issue. Fortunately our brains can only pay attention to the loudest noise. If the noise is over 30dB down you will never hear it.  
how many db down is the subway sound in the various famous Carnegie hall analog recordings….hint…> 30

of course, maybe some systems / ears cant resolve the …noise…

Why introduce your own ?
Okay some of you, I worked in a recording studio. I made a dB meter when I was 13 and it was calibrated to an NIST standard as my uncle worked for NIST. I don't dispute your list of sound levels. Some of the dB reading you guys are quoting must be "L" weighted. BTW "shouting in the ear" is way higher than 110dB!
