Sound Pressure, Sound Power, and Sound Intensity: What’s the difference? | Bsim Engineering

Sound Pressure Level | SPL Meaning, Measurement & Examples

Calculating sound pressure level using nonlinear regression: 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) are provided for a fixed number of samples. Estimate the sound pressure level (pressureEstimate) for input soundIntensity using nonlinear regression. Calculate the first-order polynomi
