Pressure and Displacement Amplitudes
Pressure and Displacement Amplitudes
The ratio of pressure amplitude to displacement amplitude is proportional to the speed of sound.
Speed of Sound
Speed of Sound
The speed of sound depends on how tightly packed (density) and how stiff (elasticity) the medium is.
Intensity of a Sound Wave
Intensity of a Sound Wave
Intensity of a sound wave is proportional to the square of the amplitude, meaning small amplitude changes greatly affect loudness.
