Place your phone next to the console. See what is it idle when you are just on the dash, and then see what it is when you are playing a game. I had a difference of 14. Someone else I did the test with had a difference of 11. If a few more people post their difference that could help people decide if they just have a sensitive ear or if they have a problem. My idle was dead quite.
Yup, that was me. I'm going to try a few other scenarios tonight just to see how much of an audible difference I can come up with.
24 idle on the right side of the console.
32 with Gears of War 4.
Very simialr to mine from last night's testing:
I measured the output with the phone directly on top of the X1X, but separated by a 1/2 rubber pad to minimize vibrations. The TV in question is a Panasonic VT65 VT65 1080P plasma, so the X1X is down sampling for my purposes.
Ambient room noise: 22-25db
As above, with X1X on at dash: 22-25db
As above, with WD 4GB My Passport Ultra plugged in: 24-27db
As above, with TV turned: on 24-27db
As above, with COD WW2 running from disc (Stronghold mission): 28-30db
As above, after disc drive shut down: 25-27db
As above, observed during 10 minute span: 25-28db
I did some further testing, and Wolfenstein averaged 33db, while Return of the Tomb Raider was 32db in performance mode, and 33db average in enhanced mode.
