Sound Class 8 Chapter 10

Sound: Its Definition and Meaning

Sound is a form of energy that travels through air or any other medium as vibrations. These vibrations reach our ears and are interpreted by our brain as sound. We are surrounded by sounds—some pleasant like music, and others less so, like traffic noise.


In simple terms, vibration is a rapid movement back and forth. This is the very essence of sound. Whether it's a guitar string or the air column in a flute, vibrations are responsible for producing sound.

Sound Produced by a Vibrating Body

Different musical instruments are designed to produce sound in different ways—some through vibrating strings like in guitars and violins, some through membranes like in drums, and some through air columns like in flutes and trumpets.

Sound Produced by Humans

In humans, sound originates from the voice box or the larynx, situated in the neck. The vocal cords vibrate when we speak or sing, thereby producing sound.

Propagation of Sound

Sound needs a medium like air, water, or solids to travel. Interestingly, sound cannot travel through a vacuum. This means, in space, no one can hear you scream!

Human Ear

Our ears are designed in a way that captures these vibrations and sends them to the brain, which then interprets them as sound. The outer part of the ear is shaped like a funnel to help guide sound into the ear canal, where it vibrates the eardrum.

Characteristics of Vibration

Three major characteristics of vibrations are its frequency, amplitude, and time period. Frequency tells us how many vibrations happen in one second. Amplitude is the size of the vibration, and the time period is how long one vibration takes.

Characteristics of Sound

Sound can be described by various properties like amplitude, frequency, and time period, which in turn define its loudness, pitch, and quality.


Loudness is directly proportional to the square of the amplitude. This is why some sounds are louder than others. Sounds that are too loud can be harmful and painful to the ear.


Pitch or shrillness of sound is determined by its frequency. A whistle has a high frequency, and thus it produces a high-pitched sound, whereas the sound of a drum is low-pitched because of its low frequency.

Audible and Inaudible Sound

Our ears can hear sounds within a specific range of frequencies. Sounds below or above this range are inaudible to humans but might be heard by other animals.

Sound Travel

Sound travels in the form of waves, forming compressions and rarefactions in the medium. The speed of sound varies depending on the medium it's traveling through.

Noise and Music

While music is pleasant, noise is considered an unpleasant, unwanted sound. Exposure to high levels of noise can be harmful and can lead to conditions like high blood pressure and even hearing loss.

Noise Pollution

Unwanted or excessive noise in our surroundings is termed as noise pollution. It's important to manage noise levels in our environment for a healthy life.

Reflection and Absorption of Sound

Sound can be reflected off hard surfaces, creating an echo, and absorbed by soft surfaces. The principles of sound reflection are utilized in technologies like SONAR and also have applications in designing concert halls and public spaces.

By understanding these aspects of sound, students can not only excel in their Class 8 Science Chapter 10 but also appreciate the fascinating world of sound around them.

In summary, the Class 8 Sound Chapter provides a detailed look into the fascinating world of sound, from its basic properties to its advanced characteristics.
