The audible range of frequency is

Options

A. 20 Hz to 20,000 Hz
B. 40 Hz to 40,000 Hz
C. 60 Hz to 60,000 Hz
D. 10 Hz to 20,000 Hz

Answer

To solve the question about the audible range of frequencies, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Concept of Audible Frequencies**:
- The term "audible range" refers to the range of sound frequencies that can be heard by the average human ear.

2. **Identifying the Frequency Range**:
- The commonly accepted audible frequency range for humans is from 20 Hz to 20 kHz.
- This means that sounds with frequencies below 20 Hz are considered infrasonic (not audible), and sounds above 20 kHz are considered ultrasonic (also not audible).

3. **Converting Kilohertz to Hertz**:
- Since 1 kHz (kilohertz) is equal to 1000 Hz, we can express 20 kHz as:
\[ 20 \text{ kHz} = 20 \times 1000 \text{ Hz} = 20,000 \text{ Hz} \]

4. **Final Statement**:
- Therefore, the audible range of frequency is from 20 Hz to 20,000 Hz.

5. **Selecting the Correct Option**:
- If given multiple-choice options, we can identify that the correct option is the one that states the range as 20 Hz to 20,000 Hz.

### Final Answer:
The audible range of frequency is from **20 Hz to 20 kHz** (or **20 Hz to 20,000 Hz**).
