Sound or noise pollution is measured in decibels, a unit that quantifies the intensity of sound. It provides a logarithmic scale to describe sound levels perceived by the human ear.

Mach numbers are used in relation to the velocity of objects moving through a fluid, most commonly applied to aircraft. It indicates the speed of the aircraft relative to the speed of sound in that medium.
The ratio of an object’s velocity to the velocity of sound in the same medium under the same conditions is called the Mach number. This dimensionless value is critical in aerodynamics and fluid mechanics, indicating the object’s speed relative to ...
The true statement for sound waves is at 0 °C their speed is 332 meters per second. Sound waves cannot be polarized because they are longitudinal waves, and they cannot travel in a vacuum as they require a medium to ...
Sound waves are longitudinal waves. They consist of compressions and rarefactions that travel through a medium, such as air, water, or solids. Unlike transverse waves, which oscillate perpendicular to the direction of wave propagation, longitudinal waves oscillate parallel to the ...
