How does audible range change?

Audible range, the spectrum of frequencies that a human can hear, typically spans from about 20 Hz to 20,000 Hz (20 kHz). This range can change due to factors such as age, exposure to loud noises, and individual variations in hearing ability. As people age, they often experience a decline in their ability to hear higher frequencies, a condition known as presbycusis. Additionally, certain medical conditions or injuries can also affect an individual's audible range.
