Quiet PC

A quiet PC is a personal computer that makes little noise. Common uses for quiet PCs include video editing, sound mixing, home servers, and home theater PCs. A typical quiet PC uses quiet cooling and storage devices and energy-efficient parts.

Like noise, the term "quiet PC" is subjective and there is currently no standard definition for a "quiet PC". However, a general definition proposed by one site is that the sound emitted by such PCs should not exceed 30 dBA. In addition to the average sound pressure level, the frequency spectrum and dynamics of the sound are important in determining if the sound of the computer is noticed. Sounds with a smooth frequency spectrum (lacking audible tonal peaks), and little temporal variation are less likely to be noticed. The character and amount of other sound in the environment also affects how much sound will be noticed or masked, so a computer may be quiet with relation to a particular environment or set of users.

Famous quotes containing the word quiet:

    You must not count much upon what I can do or learn in New York.... Everything there disappoints me but the crowd; rather, I was disappointed with the rest before I came. I have no eyes for their churches, and what else they find to brag of. Though I know but little about Boston, yet what attracts me, in a quiet way, seems much meaner and more pretending than there,—libraries, pictures, and faces in the street. You don’t know where any respectability inhabits.
    Henry David Thoreau (1817–1862)
