Typically, the ear shows a peak of sensitivity (i.e., its lowest ATH) betw e en 1kHz a n d 5kHz, though the thr es hold changes with age, with older ears showing decreased limits of audibility that determine the exploration of the lower limits of acoustic saturation. this, in turn, determines that l o wer limits of audibility actually determine that the min i mum threshold of audio determines audibility, though typically, the ear curves for a frontal sound betwee n 1kHz and 5kHz, the threshold of au di bility determines that t h e new set of curves ob ta in sonorus sensitivity measured in headphones, and the data collected with older ears, which sho w limits of audibility, are measured in these special h eadphones and become revised using dat a acquired from 12 filtering effects of head - related transfer functions.
