What am I supposed to be hearing when I listen to test tones on a perfect monitor+room setup?
Should each frequency have the same subjective loudness? ie should 25Hz sound as loud as 85Hz
Or should there be a smooth increase in subjective loudness as frequency increases?
so that 25Hz is not as subjectively loud as 85Hz
My test tones are pure sine waves from G# -1 25.956 Hz to E1 82.407 Hz, going up in semitones, all at 0dBFS.
(to position a subwoofer)
Why all the decimals, I know, but at least I can get that right.
I listen to the tones on Sony MDR 7506 headphones. There is a gradual crescendo. Subjective volume starts quiet at 25Hz and gets pretty loud by 85Hz (all tones are 0dBFS). Is this what would happen under ideal monitoring conditions, should I aim for this with my monitor/room setup?
