The decibel scale for measuring sound intensity describes how powerful a sound is. Zero decibels is the quietest sound an average huma

decibels is where sound starts to cause pain. The function D(1) =10 log

calculates the decibel level, where I is the intensity of the sound

measured in watts of power per square meter. Use this function to find the decibel level of a jet plane with the given intensity. Round your answer to one

decimal place.

10-12

Jet plane: Intensity =9.7 x 102 watts per square meter

The sound of a jet plane is approximately

decibels.
