A roar is a deep, bellowing outburst of sound forced through an open mouth. It is produced by animals of certain species. A roar is usually made using hyoid, a small bone which is not completely rigid in adults. Animals roar for various reasons, including territorial proclamation, communication with other members, and anger. Additionally, the roar of an animal such as a lion is used in the process of finding and competing for a mate.
The roar pattern is composed of three overall segments - a beginning segment sounding like moaning, a middle segment with low frequency loud tones and a final segment which sounds much like grunting. The lion's roar is familiar to many through its inclusion in the MGM opening sequence. This roar segment consists only of the middle portion of the roar, omitting the first and last portions.
Famous quotes containing the word roar:
“In clear weather the laziest may look across the Bay as far as Plymouth at a glance, or over the Atlantic as far as human vision reaches, merely raising his eyelids; or if he is too lazy to look after all, he can hardly help hearing the ceaseless dash and roar of the breakers. The restless ocean may at any moment cast up a whale or a wrecked vessel at your feet. All the reporters in the world, the most rapid stenographers, could not report the news it brings.”
—Henry David Thoreau (1817–1862)
