Audio Perception in Humans

Humans can perceive audio frequencies within the range of 20 Hz to 20 kHz.

Sound Waves in Air

The wavelength range of sound waves in air at atmospheric pressure varies inversely with frequency.

Classification of Sound Waves

Sound waves with frequencies above 20 kHz are known as ultrasound.
Sound waves with frequencies below 20 Hz are known as infrasound.

Acoustics

Acoustics is the interdisciplinary science that deals with the study of mechanical waves in gasses, liquids, and solids, including vibration, sound, ultrasound, and infrasound.

Temperature at the Particle Level

Temperature describes the average kinetic energy of particles at the particle level.

Distinction between Sound and Wind

At the particle level, sound is distinguished from wind by the coordinated motion of particles, whereas wind is characterized by random motion.

Particle Correlations in Ideal Gases

In an ideal gas, there are no correlations between particles.

Behavior of Sound at the Particle Level

Sound behavior at the particle level is characterized by coordinated oscillations of particles.

Main Distinction between Sound and Wind

The main distinction between sound and wind behavior at the particle level is the coordinated motion of particles in sound waves versus the random motion of particles in wind.
