The pitch of a sound is how high or low it is. If you think of a piano, high notes have a high pitch and low notes have a low pitch.

Question 10

Why can we hear sound better when it's loud?

Accepted Answer

Loud sounds have bigger vibrations, so they travel better through the air. This makes it easier for our ears to pick them up.

Question 11

Can animals hear sound?

Yes, animals can hear sound, and some animals can hear better than humans. Dogs, for example, can hear higher sounds than we can.

Accepted Answer

Sound needs something to travel through, like air, water, or even solid objects. It can't travel in empty space like outer space.

Accepted Answer

We hear echoes because sound waves bounce off surfaces and come back to our ears. It's like the sound waves are reflected, just like light bounces off a mirror.

Question 15

When you hear your own voice, you're hearing it from inside your head and outside your head. A recording only plays the outside sound, so it sounds different.

Question 17

Do bigger things make deeper sounds?

Accepted Answer

Usually, yes. Bigger things often vibrate slower, making deeper, lower sounds. That's why big drums sound deeper than small ones.

Question 18

Accepted Answer

The speed of sound is how fast sound waves travel. In the air, sound travels at about 343 meters per second, which is super fast!

Question 19
