I know you're not asking about speculation. My concern is the accuracy of Hania's PTA as you've pulled me up over my suggestion of hidden hearing loss (as I didn't look at the audiogram properly at first). I don't expect Hania to know the exact type of headphone used but special ones are required for extended high frequency audiometry (i.e. not standard audiometric headphones). How do I/we know that her thresholds at frequencies higher than 8kHz are accurate? -5/-10dB hearing thresholds at 20kHz for a 20year old with history of more than one acoustic trauma!? Wouldn't you be a bit skeptical?
Hey i dont quite understand, is my hearing too good for all those acoustic traumas?
