What is the proper loudness for listening?

I typically listen at 75-80 dBSPL C weighted. 

@chester_bunger re your question about Android SLM app, I believe they are problematic without calibration.  Unlike iPhones, which all use the same mic calibration, android phones do not adhere to a standardized mic sensitivity spec. 

I use Decibel X Pro on a Samsung Galaxy S9+, and using a calibrated Sound Level Meter I found I needed to introduce almost 15 dB of calibration offset to get an accurate SPL reading! Fortunately this app allows for calibration...not all do.

If this is not an option, even a relatively inexpensive Sound Level Meter is a useful tool to have for someone interested in audio.  I would recommend one with both A and C weighting, and Fast and Slow response.  They are available on Amazon for under $40.  While not lab grade, they would be much better than an uncalibrated Android app.

For me it is just before the pass labs needle begins to move unless I've got a snoot full and the woman is away. Peace and Nirvana through music!

....just kidding.

I agree with Paul McGowan. I don’t pay attention to db levels as my guide. My guide is what the particular music should be played at to be in proportion if it were live, and per where I am ‘sitting’ for the performance. Of course, I play a lot of acoustic music, where that is more easily defined in ‘size’.

The db levels are informative to a point. What’s the ambient noise level of your room?

I don’t have to listen LOUD to get it, but if I crank it a bit more than mild, I’ll energize the room with the subs and can get more. It is not necessarily better, I listen to tonality, texture and a "filled in" dimensional sound- I usually start with the midrange anyway, if that isn’t grainless and transparent, I’m out. But in terms of volume level, depending on how loudly a particular level is cut into a specific pressing, there’s an ideal loudness level within a range. Beyond that, you aren’t going to get more. Is it a system failing? if so, I don’t care at this point.

Be happy, don’t worry. Or something.
