absorb sound
diffuse sound
reflect sound
The fins on ceiling of the concert hall are to
absorb sound
reflect sound
diffuse sound

All of the Above
You and your parents inspect an empty house with the hopes of buying it. You walk through the rooms talking to one another, and you notice that your voices and footsteps are echoing in the big, empty house. What causes the echo?
sound waves reflecting off smooth, flat surfaces throughout the house
sound waves moving around the large rooms
sound waves moving slowly through air
sound waves refracting around corners in the empty rooms
Which of the following pipes on the instrument above most likely has the highest pitch when air is blown through it?
A
B
C
D
How does this instrument make sound?
The musician blows into a mouthpiece.
The wind causes the strings to vibrate.
As the bow goes across the strings, it causes vibrations in the violin.
Why is the concert hall floor covered with carpet?
So everyone can make a lot of noise
to help absorb sounds to keep it quiet
because it looks good
to help absorb sounds so it can stay noisy
If you walk into the empty school gym and yell, why would you hear an echo?
The gym walls are soft and uneven.
The sound waves are being absorbed by the hard smooth walls.
The sound waves are bouncing off the hard smooth gym walls.
The gym walls are really clean.
What is the bouncing back of a wave that hits a surface?
Refraction
Diffusion
Reflection
Diffraction
