Sound is the result of vibrations. Vibration is simply the moving back and forth of the object. But in order for these vibrations to be heard, they must take place in some medium, something to carry the sound from its source to the hearer. That medium may be air, a liquid, or a solid.
When the vibration is very regular, that is, when the sounding body sends out waves at absolutely regular intervals, the result is a musical sound. If the vibration is not regular, the effect on your ears is not at all pleasing. The resulting sound is “noise”.
The three differences between one sound and another are loudness, pitch, and tonal quality. The loudness of a sound depends partly on the distance from the object to the tar and partly on the amplitude of vibration of the sound-making object. Amplitude means the distance the vibrating body moves in its to-and-fro motion. The greater this movement is, the louder the sound will be.
The highness or lowness of a sound is called its “pitch”. Pitch de- pends on the speed of vibration of the sounding object. The greater the number of vibrations that reach the ear every second, the higher will be the pitch.
Even when two sounds may be of the same pitch and loudness, they can sound different. The quality of a musical sound depends upon the number and strength of the “overtones” present in the sound. If a violin string is made to vibrate in one long vibration throughout its entire length, it gives the lowest tone that it can make. This note is called “the fundamental”. If the string vibrates in more than one part, higher-pitched notes are heard. They blend with the fundamentals to create the particular “violin” quality. vi»n higher notes are the overtones. They create the tonal quality or « sound.
What Are Examples Of Noise?
Noise is defined as a sound, especially a loud one. An example of noise is the sound of fireworks. A complaint or protest.
What are the 3 kinds of noise?
physical, semantic, psychological, and physiological
What is noise simple?
I think the biggest challenge to noise pollution is that most people don’t even know they’re being affected by it. A recent study found that some people are unaware of how loud their TV or MP3 player, and their music, game, or app, are.
What is noise and its effects?
Noise is a familiar occurrence to many of us and is everywhere we go. From the sounds of our surroundings to the music we listen to, to the radio; noise is all around us. And the effects of noise can be both positive and negative. Some benefits of noise include acting as a form of entertainment, alerting us to changing situations, and helping us become more aware of our surroundings. However, noise can also cause us to focus on something that is unimportant rather than what is important, cause disturbances in some parts of our brains, and affect our sleep.
