No, 'reference level is for a volume setting of 0dB
on the D2v
Reference tones can be mastered at either -20dBFS to read 85dB(C, slow) using an SPL meter or -30dBFS to read 75dB(C, slow) using an SPL meter. Both will result in the same reference level, ie if you calibrate to 75dB using -30dBFS tones, -20dBFS tones will playback at 85dB at the same master volume.
The D2v's internal test tones under 'level calibration' are mastered at -30dBFS which means calibrating to 75dB(C, slow) will result in reference level at master volume 0dB
Am i getting deaf?
Everyone's hearing degrades as we age, but your just assuming reference level is 10dB lower than it actually is.
Are movies supposed to be listened at 75dB in the home?
No, they are mastered to be played back at reference level, otherwise whispers and other soft sounds get lost in the noisefloor and loud bangs, explosion, etc don't have the intended impact.
The 'recommendation' for movies to be played back at 10dB below reference for home theaters is simply because reference level is loud, it can be uncomfortable in rooms not properly acoustically treated and many home systems cannot reach reference level without distorting.
In the end, you've got the remote so it's up to you what volume you listen at.
