Answer

To answer the question, "What do you call the range of sound that is audible to human beings?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Concept of Sound**:
- Sound is a type of energy that travels in waves and can be heard when it reaches a person's or animal's ear.

2. **Defining the Audible Range**:
- The audible range refers to the range of sound frequencies that human beings can hear.

3. **Identifying the Frequency Limits**:
- The audible range for humans is typically between 20 Hz and 20,000 Hz (or 20 kHz). This means that sounds with frequencies lower than 20 Hz are not audible to humans, and sounds with frequencies higher than 20,000 Hz are also not audible.

4. **Terminology**:
- Sounds within the audible range (20 Hz to 20,000 Hz) are referred to as "sonic sounds."
- Sounds below 20 Hz are called "infrasonic."
- Sounds above 20,000 Hz are called "ultrasonic."

5. **Conclusion**:
- Therefore, the range of sound that is audible to human beings is called the "audible range," and the sounds within this range are known as "sonic sounds."

### Final Answer:
The range of sound that is audible to human beings is called the **audible range** or **sonic sounds**.
