The range of sound intensities that the human ear can detect is so large that a special decibel scale (named after Alexander Graham Bell) is used to measure and compare sound intensities. The decibel level (dB) is given by

\[ dB(I) = 10 \log\left(\frac{I}{I_0}\right) \]

where \( I_0 \) is the intensity of sound that is barely audible to the human ear. Use the decibel level formula to find the decibel level for the following sounds. Round to the nearest tenth of a decibel.

(a) Automobile traffic, \( I = 1.58 \times 10^8 \cdot I_0 \)
\[ \_\_\_\_ \text{dB} \]

(b) Quiet conversation, \( I = 10,800 \cdot I_0 \)
\[ \_\_\_\_ \text{dB} \]

(c) Fender guitar, \( I = 3.16 \times 10^{11} \cdot I_0 \)
\[ \_\_\_\_ \text{dB} \]

(d) Jet engine, \( I = 1.58 \times 10^{15} \cdot I_0 \)
\[ \_\_\_\_ \text{dB} \]
