Options

A. 60 decibels
B. 80dB
C. greater than 140 dB
D. 180 dB

Answer

To determine the noise value of moderate conversation, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Noise Value**:
- Noise value refers to the measurement of sound intensity, which is quantified in decibels (dB).

2. **Know the Unit of Measurement**:
- Decibels (dB) are the units used to measure sound. The higher the decibel level, the louder the sound.

3. **Identify the Decibel Range for Normal Sounds**:
- Normal ambient sounds are typically measured between 40 to 45 decibels.

4. **Determine the Decibel Level for Moderate Conversation**:
- Moderate conversation is generally considered to be around 60 decibels. It can be noted that it is usually under 65 decibels.

5. **Differentiate Between Noise Levels**:
- Loud noises are classified as being more than 85 decibels. For example, rock concerts can reach levels of 120 decibels.

6. **Select the Correct Answer**:
- Given the options, moderate conversation falls under 60 decibels, making option A (60 dB) the correct answer.

### Final Answer:
The noise value of moderate conversation is **60 decibels**.
