Sound Level Meter

A sound level meter or sound meter is an instrument which measures sound pressure level, commonly used in noise pollution studies for the quantification of different kinds of noise, especially for industrial, environmental and aircraft noise. However, the reading from a sound level meter does not correlate well to human-perceived loudness, which is better measured by a loudness meter. The current international standard that specifies sound level meter functionality and performance is the IEC 61672:2003.

Famous quotes containing the words meter, sound and/or level:

    His meter was bitter, and ironic and spectacular and inviting: so was life. There wasn’t much other life during those times than to what his pen paid the tribute of poetic tragic glamour and offered the reconciliation of the familiarities of tragedy.
    Zelda Fitzgerald (1900–1948)

    A village seems thus, where its able-bodied men are all plowing the ocean together, as a common field. In North Truro the women and girls may sit at their doors, and see where their husbands and brothers are harvesting their mackerel fifteen or twenty miles off, on the sea, with hundreds of white harvest wagons, just as in the country the farmers’ wives sometimes see their husbands working in a distant hillside field. But the sound of no dinner-horn can reach the fisher’s ear.
    Henry David Thoreau (1817–1862)

    Alle fresh the level pasture lay,
    And not a shadowe mote by seene,
    Save where full fyve good miles away
    The steeple towered from out the greene,
    Jean Ingelow (1820–1897)
