A healthy human ear is typically capable of hearing frequencies ranging from approximately 20 to 20,000 hertz (Hz).21
While this represents the standard audible spectrum, it is important to note that human hearing sensitivity is not uniform across this range; it is generally most acute between 500 and 10,000 Hz. Additionally, this range is subject to change over time. The natural aging process often leads to a gradual reduction in the ability to perceive higher frequencies, a decline that typically becomes more pronounced after age 50.23
