Brake - Noise

Noise

Although ideally a brake would convert all the kinetic energy into heat, in practice a significant amount may be converted into acoustic energy instead, contributing to noise pollution.

For road vehicles, the noise produced varies significantly with tire construction, road surface, and the magnitude of the deceleration. Noise can be caused by different things. These are signs that there may be issues with brakes wearing out over time.

Famous quotes containing the word noise:

    You may say a cat uses good grammar. Well, a cat does—but you let a cat get excited once; you let a cat get to pulling fur with another cat on a shed, nights, and you’ll hear grammar that will give you the lockjaw. Ignorant people think it’s the noise which fighting cats make that is so aggravating, but it ain’t so; it’s the sickening grammar they use.
    Mark Twain [Samuel Langhorne Clemens] (1835–1910)

    The noise of battle hurtled in the air,
    Horses did neigh, and dying men did groan,
    And ghosts did shriek and squeal about the streets.
    William Shakespeare (1564–1616)

    With the noise of the mourning of the Swattish nation!
    Fallen is at length
    Its tower of strength;
    Its sun is dimmed ere it had nooned;
    Dead lies the great Ahkoond,
    The great Ahkoond of Swat
    Is not!
    George Thomas Lanigan (1845–1886)
