Question

What are the sources of sound?

Answer 1

Hint: Sound can travel through a medium such as air, liquid, and solids. The types of sources are introduced: natural (e.g., from lightning, the cosmos, and the sun ); and artificial (e.g., from external sources such as power lines and combustion systems and sources inside to a receiving system connected with electronic devices and elements).

Complete step-by-step solution:
In physics, sound is a vibration propagating as an acoustic wave through a transmission medium such as a gas, liquid, or solid. Sound can be viewed as a motion of a wave in the air or another elastic medium. In this case, the sound is the motive. Sound can also be observed as an excitation of the listening mechanism that results in the sound idea. In this case, the sound is a sensibility.
The sound waves are produced by a sound source, such as the vibrating diaphragm of a stereo speaker. The sound source produces vibrations in the neighbouring medium. As the source remains to vibrate the medium, the vibrations travel away from the source at the sound speed, thus creating the sound wave at a constant distance from the source; the medium's velocity, pressure, and displacement change in time.
Sound is generated by vibrating objects and moves the listener's ears as waves in the air or other media. When an object fluctuates, it causes small changes in air pressure. These air pressure variations travel as waves by air and provide sound.
The cause of sound can be both natural or artificial. Few natural sound causes are humans, flowing water, wind, flowing streams, animals, avalanches, and many more. Sources of artificial sounds are factories, fans, automobiles, airplanes, helicopters, trains, explosions, home appliances such as vacuum cleaners.

Note:The human voice consists of sounds provided by a human being using the vocal region, including talking, chanting, laughing, crying, yelling, shouting. The frequency of the human voice is specifically a part of human sound generation in which the vocal cords are the fundamental sound source.
