Down concentration gradients.
Longitudinal waves cause particles of the medium to vibrate parallel to the direction the waves travel. In these waves, compressions (areas of high pressure) and rarefactions (areas of low pressure) move in the same direction as the wave propagation, causing the particles to oscillate back and forth in the direction of wave motion. Sound waves are an example of longitudinal waves.
Particles moving from problem areas to less crowded areas are called diffusion. Diffusion is the process by which particles spread out and move from areas of high concentration to areas of low concentration to create equilibrium. This movement occurs due to the natural random motion of particles.
A sound wave travels through a medium in alternating areas of compression and rarefaction. In compression, particles are close together, while in rarefaction, particles are spread farther apart. This alternation creates the oscillating pattern that transmits sound energy.
A longitudinal wave has areas where particles are spread out. In this type of wave, particles move parallel to the direction of the wave propagation, causing areas of compression (particles close together) and rarefaction (particles spread out). Sound waves are an example of longitudinal waves.

Down concentration gradients.
Neither of them require energy. that is the major difference.
The movement of particles down a concentration gradient in diffusion helps to evenly distribute substances in a solution. This process occurs naturally as particles move from areas of high concentration to areas of low concentration, leading to a balanced distribution of substances throughout the solution.
The process that moves particles from areas of high concentration to areas of lower concentration is called diffusion. During diffusion, particles spread out to achieve an equilibrium, where their concentration is uniform throughout the space. This process occurs naturally and does not require energy input. If the movement involves a selectively permeable membrane, it may also be referred to as facilitated diffusion.
Particles diffuse due to random thermal motion, which is driven by temperature and concentration gradients. When there's a difference in concentration between two regions, particles move from areas of higher concentration to areas of lower concentration in an effort to achieve equilibrium. This movement occurs spontaneously, as particles collide and spread out, resulting in diffusion. Thus, it's not that particles "know" when to diffuse; rather, they naturally tend to move towards areas of lower concentration due to random motion and entropy.
Longitudinal waves cause particles of the medium to vibrate parallel to the direction the waves travel. In these waves, compressions (areas of high pressure) and rarefactions (areas of low pressure) move in the same direction as the wave propagation, causing the particles to oscillate back and forth in the direction of wave motion. Sound waves are an example of longitudinal waves.
It needs particles, so Air, Liquid or Solid to travel. so the medium is any particles, so if there is no particles, sound cannot travel.
These waves are called sound waves. Sound waves are mechanical waves that travel through a medium, such as air or water, in the form of compressions (areas where particles are close together) and rarefactions (areas where particles are spread apart).
Particles moving from problem areas to less crowded areas are called diffusion. Diffusion is the process by which particles spread out and move from areas of high concentration to areas of low concentration to create equilibrium. This movement occurs due to the natural random motion of particles.
You are describing the process of diffusion.
When particles move to a less concentrated place, it is called diffusion. This process occurs as particles naturally spread out from areas of higher concentration to areas of lower concentration in an attempt to achieve equilibrium. Diffusion is a passive process and occurs in gases, liquids, and even solids. It plays a crucial role in various biological and physical processes, such as gas exchange in the lungs.
