While the sound waves travel in a medium, let's say a fluid, what is the difference between fluid pressure and acoustic pressure ? Are these entities same?
Acoustic pressure is the pressure that is created by sound waves, while fluid pressure is the pressure exerted by a fluid on its surroundings. Acoustic pressure is a type of mechanical pressure, while fluid pressure is a type of hydrostatic pressure.
Acoustic pressure is typically measured in units of decibels (dB), while fluid pressure is measured in units of force per unit area, such as pounds per square inch (psi) or pascals (Pa).
Acoustic pressure is important in various applications such as noise control, sonar, and musical instruments. Fluid pressure plays a crucial role in hydrodynamics, engineering, and many other fields.
Exposure to high levels of acoustic pressure can damage the human ear and cause hearing loss. Fluid pressure can also have significant effects on the human body, such as the sensation of pressure in the ears when diving or flying in an airplane.
No, acoustic pressure and fluid pressure are two distinct types of pressure and cannot be directly converted into each other. However, changes in one type of pressure can affect the other, such as sound waves causing changes in fluid pressure.
