Equal loudness curve testing - Page 4

post #46 of 49

Some interesting "Equal Loudness Curve" experimements at hearing threshold levels, can be performed online:

 

http://mynoise.net

 

1. Calibrate http://mynoise.net/calibration.php

2. Play back any noise (such as the rain noise here http://mynoise.net/NoiseMachines/rainNoiseGenerator.php)

3. Load your personal calibration curve, by clicking the "Personal Curve" setting (and see the sliders move to your hearing thresholds)

 

Although I agree one shouldn't use the Equal Loudness Curve to equalize your audio equipment - it is still a nice trick to compensate for your ageing hearing loss...

Here is mine.  I used my DT880s for this, and my T1 also yielded the same results.  I was unable to detect 16 kHz.

I'm going to retry the equal-loudness curve on my new DAC and headphone setup. See if what the differences are between

and

Make sure that you match levels as close as possible, because even small changes in SPL will cause differences in how loud your perceive low frequencies.
