Pressure and Displacement Amplitudes

The ratio of pressure amplitude to displacement amplitude is proportional to the 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 is proportional to the square of the amplitude, meaning small amplitude changes greatly affect loudness.

Sound Level in Decibels

Decibels use a logarithmic scale to measure sound intensity, making it easier to represent a wide range of sound levels.

Displacement and Pressure Amplitudes

As displacement amplitude increases, the pressure amplitude also increases proportionally.
