My ears must still be pretty good despite all the damage, I can hear the test up to 13khz, but 14 and above I can't hear.
Better than I would have thought.
Bass frequencies are funny, i can't really hear them below 40hz, but I can tell if they are missing from music or if the sub is turned off. 20hz-40hz translate to feeling more than hearing. When its there, the music is great, when its not, music is lacking.
I have sub that I built that will do an honest 110db at 20hz, so it is very evident when those low notes are there or not.
