Sorting Sounds That Are Loud or Quiet

with Atlas

Atlas stands in a busy schoolyard at recess, holding one hand cupped behind his ear with a big smile, while a drum booms nearby and a butterfly lands silently on a flower beside him.

Identify whether a sound is loud or quiet by listening and comparing.
Sort everyday sounds into loud and quiet groups.
Compare two sounds and explain which one is louder.
Identify a quiet sound from a group of everyday sounds.

Key terms

loud: a big strong sound that is easy to hear
quiet: a small soft sound you must listen closely for
volume: how loud or quiet a sound is
compare: to listen to two sounds and tell which is louder
sort: to put things into groups that go together

Loud Sounds and Quiet Sounds

How loud or quiet a sound is can be called its volume. A loud sound, like a booming drum or a fire truck siren, is strong and fills the whole room so you might want to cover your ears. A quiet sound, like a whisper or rustling leaves, is soft and gentle, so you have to lean in and listen carefully to hear it.

Comparing Two Sounds

Comparing means listening to two sounds and deciding which one is louder. A hand clap is louder than a finger snap. A fire truck siren is louder than a purring kitten. The size of the animal or object does not always tell you the volume — you have to actually listen and compare the two sounds to be sure.

Worked examples

Atlas hears a whisper and a hand clap. Which sound is louder?

Listen to the whisper — it is soft, so you must lean in to hear it.
Listen to the hand clap — it is strong and fills the air.
Compare the two and choose the bigger sound.

Answer: The hand clap is louder than the whisper.

Hey there! I am Atlas, and today we are going on a listening adventure! Sounds can be LOUD or QUIET. A loud sound is big and strong. It fills up the whole room. A quiet sound is small and soft. You have to listen closely to hear it. Think about a big drum — BOOM! That is loud. Now think about a whisper — shhhh. That is quiet. Here is a fun trick: if a sound makes you want to cover your ears, it is probably loud. If you have to lean in to hear it, it is probably quiet. We can also COMPARE sounds. That means we listen to two sounds and ask: which one is louder? A clap is louder than a snap. A fire truck siren is louder than a purring cat. You can sort sounds just like you sort blocks by color. Put the loud ones in one pile and the quiet ones in another. Ready to try?

Activity

Read about each sound, then drag it into the loud or quiet bucket.

Practice

Name one loud sound and one quiet sound from your day.

Which is louder, a purring cat or a booming drum?

Common mistakes to avoid

All animals make loud sounds.Many animals are quiet, like a softly purring kitten, so animals are not always loud.
Bigger things always make louder sounds.Size does not decide volume — a small siren can be much louder than a big quiet pillow.

Check your understanding

A fire truck drives by with its siren on. Is that sound loud or quiet?

Atlas hears two sounds: a whisper and a hand clap. Which one is louder?

A kitten purrs softly next to you. That sound is —

Atlas is sorting sounds. Which of these would he put in the quiet group?

Recap

Sounds can be loud or quiet, and we call this their volume. Loud sounds are strong and fill the room, while quiet sounds are soft and need close listening. We can compare two sounds to decide which one is louder and sort them into groups.

Reflect

What is the quietest sound you can hear right now?
