What is the difference between sound pressure and sound power, and how do they relate to each other in the context of acoustics?

Sound pressure refers to the force exerted by sound waves on a surface, measured in units like pascals. Sound power, on the other hand, is the total energy output of a sound source, measured in watts. In acoustics, sound pressure is directly related to sound power, as the intensity of sound waves determines the pressure they exert. Sound power is the source of sound pressure, with higher power leading to higher pressure levels.
