Chapter 10: Q. 10.52 (page 1031)

What is the decibel level of heavy city traffic with intensity $10^{- 3}$ watts per square inch?

Short Answer

Expert verified

The decibel level of heavy city traffic is $90 d b$ .

Step by step solution

Step 1. Given information.

The given intensity is $10^{- 3}$ watts per square inch.

ere the loudness level, D, measured in decibels, of a sound of intensity, I, measured in watts per square inch is

$D = 10 \log (\frac{I}{10^{- 12}})$ .

Step 2. Finding the decibel level.

Here the intensity is $10^{- 3}$ watts per square inch then the decibel level is

$D = 10 \log (\frac{I}{10^{- 12}}) = 10 \log (\frac{10^{- 3}}{10^{- 12}}) = 10 \log (10^{9}) = 9 \times 10 = 90$

Therefore, the decibel level of heavy city traffic is $90 d b$ .
