Question
The range of audible frequency for the human ear is
Options
2 Hz to 2000 Hz
20 Hz to 2000 Hz
20 Hz to 20000 Hz
200 Hz to 20000 Hz
Solution
20 Hz to 20000 Hz
Explanation:
- Frequencies below 20 Hz are infrasonic and cannot be heard.
- Frequencies above 20 kHz are ultrasonic and are inaudible to humans.
- Hearing ability declines with age, especially for higher frequencies.
- Some animals can hear beyond this range (e.g., dogs and bats).
Thus, humans can hear sounds in the 20 Hz to 20 kHz range.
