Identify the frequency range of sounds audible to humans.

Options

A. 0 Hz-20,000 Hz
B. 20 Hz-20,000 Hz
C. 0 Hz - 200,000 Hz
D. 20 Hz - 200,000 Hz

Answer

To identify the frequency range of sounds audible to humans, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Sound Frequencies**:
- Sound waves are classified based on their frequency, which is measured in Hertz (Hz).

2. **Identifying Infrasonic Sounds**:
- Frequencies below 20 Hz are classified as infrasonic sounds. These sounds are not audible to humans.

3. **Identifying Ultrasonic Sounds**:
- Frequencies above 20,000 Hz are classified as ultrasonic sounds. These sounds are also not audible to humans.

4. **Determining the Audible Range**:
- The range of frequencies that humans can hear lies between the infrasonic and ultrasonic ranges. This is from 20 Hz to 20,000 Hz.

5. **Conclusion**:
- Therefore, the frequency range of sounds that are audible to humans is from 20 Hz to 20,000 Hz. This range is commonly referred to as the "audible range."

### Final Answer:
The frequency range of sounds audible to humans is **20 Hz to 20,000 Hz**.
