Question

What is the approximate range of audible sound frequencies for a human with good hearing?

• A. From $20Hz$ to $2000Hz$
• B. From $20Hz$ to $20000Hz$
• C. From $200Hz$ to $20000Hz$
• D. From $200Hz$ to $200000Hz$

Answer 1

The correct option is B From $20Hz$ to $20000Hz$

Adult humans can hear from $20Hz$ to $20000Hz$ of frequency. Sound with frequency lower than $20Hz$ are called infrasonic, and higher than $20000Hz$ are called ultrasonic or supersonic which are inaudible to humans.
