What are Acoustics?
How sound behaves in different environments.
How light waves travel through space

The process of converting electricity into sound.
What is a Decibel?
A unit that measures the loudness of sound
A musical note used in high-pitched songs
A unit that measures the speed of sound
A type of battery that powers audio equipment
What happens when sound waves reflect?
They bounce off surfaces and travel back to the source
They disappear in open spaces.
They speed up in the air
They scatter in many directions
What is sound absorption?
The process of materials soaking up sound and reducing reflection
The process of increasing the volume of sound
The way sound travels through empty space.
The method of changing sound into light waves.
What is sound diffusion?
The scattering of sound waves in many directions
The process of sound being absorbed by soft materials
The splitting of sound into completely separate frequencies.
The ability of sound to be stored and reused.
What is an echo?
A reflected sound wave that can be heard after bouncing off a surface.
A sudden increase in the speed of sound.
A sound wave that is completely absorbed by a surface.
A type of musical instrument that produces repeating sounds.
What is echolocation?
A method used to move around a space by creating a sound and listening for the echo to know where objects are located
The ability of animals to see in complete darkness.
A way to send messages using low-frequency radio waves.
A process where sound waves travel faster than light.
What is the frequency range of human hearing?
20 Hz to 20,000 Hz
200 Hz to 200,000 Hz
2 Hz to 2,000 Hz
1,000 Hz to 100,000 Hz
What is Ultrasound?
Sound waves with frequencies higher than 20K Hz
A type of sound that can be heard by all animals.
A musical technique used to create high-pitched tones
A sound that only occurs in outer space.
What is Infrasound?
Sound waves with frequencies lower than 20 Hz
A method used to amplify very weak sounds.
A sound used in music production to make beats louder.
A type of noise created by electronic devices.
What is the unit "Hertz" used to measure?
The frequency (speed) of sound waves.
The loudness of sound.
A measurement for how far a sound wave can travel.
The conversion of sound into electric signals
What is Noise Pollution?
Unwanted or harmful sound that disrupts the environment or human health
A way to block unwanted sound using special walls.
The process of removing sound from an environment.
A type of sound that only exists underwater.
Creating mass along a wall helps acoustics by...
Reducing the sound from a neighboring room
Reflecting sound back towards students
Diffusing sound waves to all parts of the room
Soundproofing the room from all reflections
Acoustical tiles in the ceiling are helpful to classroom acoustics because...
They absorb all sound waves
They absorb vertical sound waves
They absorb horizontal sound waves
They do not absorb sound waves
Reflective surfaces in a classroom are helpful when...
They are placed behind the teacher to reflect their voice back to the students
They are placed on the back wall to reflect to students in the back of the room
They are placed in the corners to diffuse the sound to all students
It is never helpful to have a reflective surfaces in a classroom
