2. A sound changes from an intensity of $5 \times 10^{-6} \text{ W/m}^2$ to $5 \times 10^{-7} \text{ W/m}^2$. a) Has the sound intensity level increased or decreased? b) By how much has the sound intensity level changed in decibels?

Find the intensity levels in decibels for sounds with intensities of (a) $10^{-2} \mathrm{~W} / \mathrm{m}^{2},$ (b) $10^{-6} \mathrm{~W} / \mathrm{m}^{2},$ and (c) $10^{-15} \mathrm{~W} / \mathrm{m}^{2}$
The decibel level for the intensity of a sound is a logarithmic scale defined by $D=10 \log _{10} I+120$, where $I$ is the intensity of the sound in watts per square meter. (a) Express $I$ as a function of $D$. (b) Show that when $D$ increases by 20 , the intensity increases by a factor of 100 .

The sound intensity level is reported in decibels. If one doubles the intensity of sound, by what does the perceived loudness, in decibels, change? (a) 2 dB (b) 3 dB (c) 5 dB (d) 10 dB (e) 20 dB
