Applications of Exponential and Logarithmic Functions

Using log properties, find a simplified formula for the difference between the two ratings, , in terms of the two intensities, and . (Decibels are introduced in the text on page 163.) Solution: B. If a sound’s intensity doubles, how many decibels louder does the sound become? Solution: so . So of sound intensity doubles, the decibel rating goes up by approximately 3 dB.
