One Hertz (Hz) is one vibration per second. Higher Hertz values equate to higher pitched sounds.
Most people hear between 20 to 20,000 Hertz, but different people can have different hearing ranges. Some people can hear at 22,000 Hz and higher. Genetic inheritance can affect hearing ability just like it affects so many other traits, but there can be losses to the ability to hear the full audio spectrum, and specifically high frequencies, as we age or if damage caused by exposure to loud noises occurs. It can be normal for a middle aged man to only hear as high as 13,000 Hz. Hearing tends to deteriorate more slowly in women which is why woman often hear higher pitches more than same-aged males.
