Sound pressure and intensity are distinct quantities interconvertible by a known relationship

Evidence

Sound pressure is defined as force per unit area (pascals or N/m2), and can be measured via movement of the diaphragm of a microphone used in a sound level meter. In contrast, sound intensity is the power carried by the sound waves per unit area and has units of watts/m2. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 683
