A EarDingens2.0 Hearing Profile shows your personal equal loudness contour. It tells you how loud you perceive a frequency compared to other frequencies. This curve is influenced by:

• your hearing ability
• your current mood / constitution
• your listening equipment like headphones / loudspeakers, preamps, ...
• influence of substances

What can you do with that?

You can track your equal loudness curve over time, so you would see any dicrease of your hearing ability. Or you can show it your sound engineer to dial in the perfect EQ for your in-ear mix.

Why should it? It's your ears, it's your perception. This data should be yours and it should be for you to decide who should see the data.
