Question

What is the audible range of a normal human ear?

Answer 1

1. The audible range of an average human ear lies between $\text{20 Hz}$ to $\text{20,000 Hz}$. Humans cannot hear sounds having frequencies less than $\text{20 Hz}$ and greater than $\text{20,000 Hz}$.
2. Hence, we can say that the human ear can hear sounds having frequencies ranging between $\text{20 Hz}$ - $\text{20,000 Hz}$. These waves are called audible waves.
