What is it?
Volume, when we talk about sound, means how loud or soft a sound is. It tells us the strength of a sound wave. A high volume means a loud sound, and a low volume means a soft sound.
Simple Example
Quick Example
Imagine you are watching a cricket match on TV at home. If you increase the 'volume' on your remote control, the commentators' voices become louder. If you decrease it, their voices become softer. That's how volume works!
Worked Example
Step-by-Step
Let's say you are listening to your favourite song on your phone.
1. You start the song, and it plays at a normal level.
---
2. You notice your younger sibling is sleeping, so you decide to make the sound softer. You press the 'volume down' button on your phone.
---
3. The sound of the song becomes less intense, making it quieter.
---
4. Later, your sibling wakes up, and you want to dance. You press the 'volume up' button.
---
5. The sound becomes more intense and louder, perfect for dancing!
---
Answer: Changing the volume button makes the sound louder or softer.
Why It Matters
Understanding volume is crucial in fields like music production, broadcasting, and even everyday communication. Sound engineers use it to balance music, while radio jockeys adjust their mic volume for listeners. Doctors also use it to explain things clearly to patients without shouting or whispering.
Common Mistakes
MISTAKE: Thinking volume only means the size of something (like a water bottle) | CORRECTION: Remember that 'volume' has two main meanings: one for space/size, and another for how loud a sound is. This page focuses on sound loudness.
MISTAKE: Confusing volume with pitch (how high or low a sound is) | CORRECTION: Volume is about loudness (e.g., a shout vs. a whisper). Pitch is about how high or low a sound is (e.g., a bird's chirp vs. a lion's roar). They are different properties of sound.
MISTAKE: Believing louder volume always means better sound quality | CORRECTION: While some sounds need to be loud, very high volume can distort sound quality or even damage your hearing. Good sound quality means clear sound, not just loud sound.
Practice Questions
Try It Yourself
QUESTION: If your teacher asks you to speak up so everyone can hear you, are they asking you to increase or decrease your voice's volume? | ANSWER: Increase
QUESTION: You are in a library, and your phone's ringtone suddenly goes off very loudly. What should you do with your phone's volume to be respectful? | ANSWER: Decrease the volume or put it on silent.
QUESTION: A Dholak player is playing for a wedding procession. To make the music more exciting and felt by everyone, what adjustment might they make to how hard they hit the Dholak, and what effect does this have on the sound's volume? | ANSWER: They would hit the Dholak harder, which increases the volume of the sound.
MCQ

What is the main difference between a whisper and a shout?
Their pitch
Their timbre
Their volume
Their echo
The Correct Answer Is:
C
A whisper is a very soft sound, and a shout is a very loud sound. This difference in loudness is what we call volume. Pitch is about how high or low a sound is, and timbre is about the quality of the sound.
Real World Connection
In the Real World
When you are on a video call with your grandparents using apps like WhatsApp or Google Meet, you often adjust the 'speaker volume' on your phone or laptop. This helps you hear them clearly if they are speaking softly, or you can lower it if their voice is too loud, making the conversation comfortable.
