Sound in our environment that we refer to as noise includes many different frequencies. When a sound signal contains es, distributed equally over the audio spectrum, it is called white noise.

Famous quotes containing the word sound:

    It is not only their own need to mother that takes some women by surprise; there is also the shock of discovering the complexity of alternative child-care arrangements that have been made to sound so simple. Those for whom the intended solution is equal parenting have found that some parents are more equal than others.
    Elaine Heffner (20th century)

    You can’t, in sound morals, condemn a man for taking care of his own integrity. It is his clear duty. And least of all can you condemn an artist pursuing, however humbly and imperfectly, a creative aim. In that interior world where his thought and his emotions go seeking for the experience of imagined adventures, there are no policemen, no law, no pressure of circumstance or dread of opinion to keep him within bounds. Who then is going to say Nay to his temptations if not his conscience?
    Joseph Conrad (1857–1924)

    Every now and then, when you’re on stage, you hear the best sound a player can hear. It’s a sound you can’t get in movies or in television. It is the sound of a wonderful, deep silence that means you’ve hit them where they live.
    Shelley Winters (b. 1922)
