"In general, the intensity of a wave is the power per unit area carried by the wave."
"The sound intensity level $\beta$ is defined to be $\beta \text{ (dB)} = 10 \log_{10}\left(\frac{I}{I_0}\right)$, where *I* is sound intensity in watts per meter squared, and $I_0 = 10^{-12} \text{ W/m}^2$ is a reference intensity."
"Sound intensity level is not the same as sound intensity—it tells you the *level* of the sound relative to a reference intensity rather than the actual intensity."
"The perception of frequency is called pitch, and the perception of intensity is called loudness."

What you'll learn
- Relate the amplitude of a sound wave to its loudness and energy
- Define sound intensity as power per unit area and compute it from power, area, or pressure amplitude
- Describe the decibel scale and compute sound intensity level using β = 10 log₁₀(I/I₀)
- Distinguish sound intensity (W/m²) from sound intensity level (dB)
- Describe how humans hear sound and how the vocal cords produce sound and control pitch and loudness
