It sucks, but you adapt with other levels. I can hear everything a turkey does except that. I have heard that a drum is on a certain decibel wavelength or whatever you want to call it. I also have been told you can feel it in your chest as much as hear it.

I was hunting with hellfighter last year and we were set up and he was motioning he could hear the gobbler drumming. I didn't hear a damn thing. Didn't "feel" it in my chest either.

An other example will serve. My son came up with something off youtube that kids were supposedly using as ringtones because alot of adults past certain age lose that level of hearing. I couldn't hear it. My wife in the other room was like "what the heck is that sound?". My son was like "Dad can't hear it".
