Understanding Human Audible Frequency

The range of sound frequencies that humans can typically hear is known as the audible range.

Audible Sound Wave Frequencies

For humans, audible sound waves fall within a specific frequency spectrum. This range allows us to perceive sound.

• Sounds with frequencies below the lower limit are called infrasound.
• Sounds with frequencies above the upper limit are called ultrasound.

Determining the Audible Range

The standard audible frequency range for healthy young humans is generally considered to be from $20\text{ Hz}$ (Hertz) to $20000\text{ Hz}$ ($20\text{ kHz}$).

• Frequencies below $20\text{ Hz}$ are too low to be heard.
• Frequencies above $20000\text{ Hz}$ are too high to be heard.

Therefore, the audible waves for humans are those with the frequency range between $20\text{ Hz}$ to $20000\text{ Hz}$.
