How quiet is your room?

I was wondering if anyone else out there has room treatments and is measuring the noise levels in their room without any sound. My main listening room is between 40-43 DB with just pure ambient noise. It will get lower, but the normal running range on my meter is between these numbers.

Are others out in the community finding much lower figures with a treated room?
If so, how did you get there?

Are others out there seeing much higher levels?

Thanks for the feedback.

I run the AC in the summer to keep the room cool due to using tubes. It can raise the ambient noise to 50db.

If I move, I'll make sure the new room has better ambient noise control and better venting to handle the heat from the tubes.
If the room is too quiet it feels wrong. Its hard to explain exactly and may not effect everyone the same way, but I just feel uncomfortable in a super quiet room.
Kind of like being in a recording studio I imagine. Just close your eyes:)
Your post got me to dig out my SPL meter to see what my room was at. I have never tried this. Don't know why, but I don't recall ever measuring it.

My meter only goes down to 50db, (actually 60db with a +/- 10 db). The meter reads LOW, so I am assuming mine is around 46db-48db or so.

I always thought the ambient noise of my room was higher than most? But, maybe not that much.

Thanks for the post!
Not far from a highway, so 50's during the day and 40's at night. Depends on weighting.
My measurement was with the AC turned off. I am just below 50db with the AC running as my room backs up to the utility room.
Using my Triplett SPL meter, right about 32-33db ... when I take a breath while measuring, it goes up to 37db :)

It's a purpose built from scratch audio room, and performs incredibly well.
So it sounds like the low reading of 32-33 in Vapor's design / built room would serve as a good low benchmark. Impressive. I wonder how much of this is the preservation of outside sound coming in, as much as the absorption of internal ambient noise.

An interesting test in Vapor's room would be to have some one make multiple 50, 60, 70 db sounds from outside the room, and see if there is a large variance in the ambient sound in the room. I have to imagine this is a combination of both, but I would like to understand the relationship between outside prevention -vs- internal room absorption.

I am thinking that this room is really well protected from outside sound coming in.

Thanks for the feedback.
