3. Sound Intensity and Pressure | Basic Acoustics

3.4 The relationship between dB SPL and dB IL. If we make certain assumptions about the nature of the sound waves (i.e. that they are what are called plane waves) then the intensity is proportional to the square of the pressure divided by a particular characteristic of the air (or whatever medium the sound is traveling in) called the "characteristic acoustic impedance".
