I'm wondering whether the frequency resolution of the inner ear increases/decreases with the volume level (caused by sound pressure $(N/m^2)$.
My assumption would be that as long as the pressure level is high enough to cause a pressure wave in the scala media/corti-organ, the frequency discrimination has nothing to do with the volume level.
There doesn't seem to be any information regarding this question!
Let me give an example to illustrate better what my question is:
If I have a sound with $20 \ dB$ and a certain frequency $1000\ Hz$ will the ability to judge the note (frequency) increase or decrease with the pressure?
