You might have heard various sounds around you.  Some sounds are pleasant while some are described as unpleasant. Pleasant sounds are ones that make you happy. Example: the sound of a water fall. Unpleasant ones give rise to headache.  The horn of cars is one such example of unpleasant sound. Thus, Sound is a type of energy made by vibrations. We will enlighten you today with various applications of sound.

Applications of Sound


  1. The sound is used for Communication:

We need sound to communicate with each other. Have you ever thought what will happen if there is no sound? We hear sounds with the help of our ears. If there is no sound, we won’t be able to communicate with each other. Therefore, sound is very important for communication.

  1. The sound is also used for measuring the surroundings:

Our surroundings play a great role in measuring the nature. It depends on the way we interact with the sound waves. There is a difference between shouting in a big room and shouting in a small room. The voice would sound different in both the case.

  1. Sound produces various frequencies:

Irregular sound waves gives rise to noise. For example, the sound produced by the horn of a car is one such example of irregular sound. The sound produced by soothing music is an example of regular sounds. Therefore, the frequency of the sound differ depending on the type of sound.

  1. Vibrations of the sound:

Sound takes place due to vibration. The pitch of the sound depends on the vibration.  If the Frequency of the vibrations are slow, it creates a low pitch. But if the frequency of the vibrations are high, it creates a high pitch.

  1. Wind instruments produce sound:

The sound is produced by the vibration of the air. It typically happens when a person blows air into the instrument. Take for instance, flute and trumpet. The air produced move back and forth creating sound waves. This is how wind instruments produce sound.

  1. String instruments make sound:

Guitar and violin are examples of string instruments. We apply a lot of pressure while playing the string instrument. It is played by pressing the fingers down on the strings. As a result, there is a change in the length of the string. The pressure applied causes the string to vibrate at different frequencies and hence produce different sound.

  1. Sounds travel under water:

It is known that sound moves at a much faster pace in the water than in the air. Sound travels four times faster in water than in the air. It is supposed that water covers long distances by travelling much faster. Whales sense each other even when they are hundred miles apart.

  1. Robert Boyle discovered the medium of sound:

Robert Boyle was the first person to discover the medium of the sound. His experiment with the clock proved famous worldwide. He put the ringing clock inside the jar in order to suck the air while the clock was still ringing.

So this is it! Now you know about Sound and its applications in real life. This article was broken into different points to make you understand the concept with examples. We have studied about sound in the our school. However, learning with examples creates a better learning experience for the reader.
