How Sounds Are Produced?
What is sound? Sounds are different kinds of noises that can come from just about anything. Sounds can be a whale in the ocean, a river flowing, a piano playing, the wind blowing, thunder and lighting, or a piece of paper rattling. Sound is energy that comes from things vibrating.
Sound comes from frequency, sound Waves, vibrations, wavelengths, amplitude, velocity of sound, echoes, and reverberation. See the Picture below. The L is the waveLength and the a is the amplitude.
Frequency is The number of soundwaves made by a vibrating object in one second. Fast vibrations create high Frequences, High pitches and high sounds. See the picture below:
<-- High Frequency = High Sound
slow vibrations create low frequencies, low pitches and low sounds. See the picutre below:
<-- Low Frequency = Low Sound
A vibration can be an echo. Wave length is the distance from one crest to the next wave. Amplitude is the distance to a crest from the base line of a wave, which is the loudness of sound. Sound is measured by decibels. Decibels can tell how high your maximum sound is on your radio or boom box. Velocity of sound involves sound through temperature. An example is a sonic barrier of an aircraft. An echo is a repeated sound that goes from high to low. Example, you can be on top of a mountain and scream a word and hear it more than once until it goes away. When an echo is confused it is called reverberation. A good example of confused sound, is someone standing on top of a mountain screaming a word, and before the word is complete, another word is added causing confusion with what is already being said. All these things in this paragraph produce sound. See the picture at the bottom of the page showing production of sound.
