Why Do Recording Studios Have Foam Wedges on the Walls?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do recording studios have foam wedges on the walls?

The Big Idea

Recording studios have foam wedges on the walls to soak up sound instead of letting it bounce! With fewer echoes, a studio can record clear sound without a roomy ring. The wedges are especially good at soaking up higher sounds.

Soft Foam

Step one: soft foam. Hard walls bounce sound, but soft, springy foam does not. Sound sinks into it instead.

Pointy Shapes

Step two: pointy shapes. Sound waves get trapped between the folds of the wedges. The foam turns the sound into a tiny bit of heat, far too small to feel.

Clear Sound

Step three: clear sound. With fewer echoes, microphones pick up just the voice or instrument. Studios also use thick curtains and special panels.

A Closer Look

Let's take a closer look! First, a voice or an instrument makes sound. The foam wedges soak it up. Fewer echoes bounce back around the room. Then the recording sounds clean and clear. Soft things tame a room.

Quick Facts

Quick facts! Quick facts about quiet rooms. Thick curtains, blankets, and clothes soak up sound. Bare, hard walls make rooms sound echoey. Wedges work best on higher sounds. Ask a grown-up to help with the test.

Think Like a Scientist

Now, think like a scientist! Ask a grown-up to record a short message on a phone in a bathroom. Then record it again in a closet full of clothes. Listen to both carefully. Which one sounds clearer, and why do you think so? Share what you discover with a grown-up.

Outro

Soft foam soaks up echoes, so recordings sound clean and clear. Science is amazing! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download! Bye for now!
