Sound Pressure vs Power
Explain the difference between sound pressure and sound power.

Hint
The SI unit for sound power is watt (
$$W=J/s$$
). The SI unit for sound pressure is pascal (
$$Pa=N/m^2$$
). To generalize, sound power is the cause, and sound pressure is the effect.
Sound power is the total sound energy radiated by a source per unit of time. Sound pressure is a measurement (at a specific location) of a sound source as it is transfers throughout a special acoustical environment. In other words, sound power is the cause, and sound pressure is the effect.
Sound pressure is a measurement (at a specific location) of a sound source as it is transfers throughout a special acoustical environment. Sound Power is the total sound energy coming from a device per unit time.
