Sound and their property and characteristics

Sound: Sound is the disturbance of the particle at a specific frequency that receives a receptor to detect

Sound is longitudinal waves traveling through a medium; without a medium, sound waves can not travel.

Production of sound: Sound can be produced by the vibration of particles, without the vibration sound can not be produced. For the production of sound the vibration of sound can must have a specific frequency.

 Detection of sound: Sound can be detected by various objects, the ear is the biological organ, the ear converts the disturbance frequency to hearing, and the mobile is also the receiver of the disturbance of the sound which converts the electromagnetic waves to sound waves, and then we can hear it.

Characteristics of sound: There are a few characteristics of sound by which we can distinguish one sound from another sound, which are given below.

1. Pitch: It is the property of sound by which we can distinguish the shrill sound from the grave sound, as the higher the frequency higher the pitch, and vice versa, which means that the pitch is directly proportional to the frequency. Therefore women's sounds are shrill because they have a high frequency and the man's sounds are grave because they have a small frequency.
2. Loudness: Sound has larger energy the loudness will be greater which means the greater the sound energy greater the loudness, it depends upon the following factors; 1: The area of the vibrating body,2: Distance from the source of the sound,3: Material through the sound is traveling.
3. Quality: This is the property of a sound by which we can distinguish two sounds of the same frequency and same loudness and same pitch is called the quality of the sound.

Sound intensity: The amount of sound energy passing through the unit area in unit time is called intensity.

Speed of sound waves: The distance traveled by the body in a unit of time is called the speed of sound. The speed of sound in air is 343m/s, sound can be transmitted through any medium. The speed of sound is the highest in the solid and the smallest in the air. The speed of sound depends on where it is passing.

Reflection of sound waves and echo: When the waves of sound are traveling and strike the barrier they will be absorbed, transmitted, or reflected. The reflection of the sound waves depends upon the nature of the medium. So can define the reflection as “the return the sound waves back when it strikes the surface is called the reflection of the sound waves.”

Echo: A sound wave reflected and we can easily distinguish between the real and reflected waves is called echo.

Acoustics: It is the study of sound waves to overcome the echo of the sound, acoustic protection is the application that is used to overcome the echo of the sound and we can able to hear the sound clearly in rooms, halls, and other places.

Audible frequency range: There are different types of sound that we can not hear so according to this scientific divide the sound into three types of frequency range. Because human beings only listen to those sound which has frequencies only from 20hz to 20 kHz. So on the basics of hearing sound can be divided into three frequency ranges

1. Ultrasonic frequency
2. Audible frequency
3. Infrasonic frequency

Now we can explain this one by one below

Infrasonic frequency: The sound energy whose frequency is less than 20hz is called infrasonic frequency which humans can not hear and whales and elephants hear and produce the infrasonic frequency sounds.

Audible frequency: The sound frequency which ranges from 20hz to 20khz is known as the audible frequency range which can humans hear and produce these sounds.

Ultrasonic frequency: The sound energy whose frequency ranges from above 20khz is known as ultrasonic frequency. Bats can hear the sound of ultrasonic and produce the sound of ultrasonic frequency.
