Sound pressure: Sound exerts pressure on the human ear. Increasing loudness corresponds to greater pressure. The table below shows the pressure P , in dynes per square centimeter, exerted on the ear by sound with loudness D, measured in decibels.
a. Plot the natural logarithm of the data. Does it appear reasonable to model pressure as an exponential function of loudness?
b. Find an exponential model of P as a function of D using the logarithm as a link.
c. How is pressure on the ear affected when loudness is increased by 1 decibel?
