The average human can detect sound in the range of 20Hz to 20kHz, and the ear is most sensitive to frequencies around 1,000-3,500 Hz.
As we age, our hearing range typically decreases and most people can only hear sounds up to 15-17 kHz.
Sensitivity to sound also varies with frequency.
Routine investigation for hearing loss usually involves an audiogram which shows threshold levels relative to a normal.

As we age, so do our inner ears. Because of this, there are certain sounds that we simply cannot hear as we get older.
