Why is sound wave of intensity `10^-12(W)/(m^2)` and frequency 1000 Hz taken as the standard for expressing the intensity level of all other sound waves?

Explanation

To understand why a sound wave of intensity \(10^{-12} \, \text{W/m}^2\) and frequency 1000 Hz is taken as the standard for expressing the intensity level of all other sound waves, we can break down the reasoning into several steps:

### Step-by-Step Solution:

1. **Understanding Sound Intensity**:
- Sound intensity is defined as the power per unit area carried by a sound wave. It is measured in watts per square meter (\( \text{W/m}^2 \)).
- The intensity level of sound is often expressed in decibels (dB), which is a logarithmic scale.
