Humans perceive sound intensity logarithmically. if the sound intensity increases by a factor of 100, then a human perceives the sound twice as loud. the sound intensity (soundintensitydata) and corresponding sound pressure level data (soundpressuredata) is provided for a fixed number of samples. estimate the sound pressure level (pressureestimate) for input soundintensity using nonlinear regression. calculate the first-order polynomial coefficients that fits the provided samples:
