What is sound intensity?
The energy of a sound wave
100
Amplitude is associated with which characteristic of sound?
Volume / loudness
100
Frequency is associated with which characteristic of sound?
Pitch
100
Hearing happens when sound waves travel to this part of the human body.
Ear
100
Sound needs to travel through matter such as air, so sound cannot be heard in this location.
Space.
200
This is a unit of sound intensity.
Decibel.
200
What is the volume of this wave?
Low volume
200
What is the frequency of this wave?
Low frequency
200
There are two main types of hearing loss, conductive and sensorineural. Which is associated with a build up of ear wax?
Conductive hearing loss
200
Sound travels at different speeds through different materials, or media. Which medium does sound travel fastest through?
a. Air
b. Water
c. Wood
c. Wood
Air: 344 m/s
Water: 1,481 m/s
Wood: 3,500 m/s
300
Which factor, amplitude or frequency, is most closely associated with the energy of a wave?
Amplitude
300
What is the volume of this wave?
High volume
300
What is the pitch of this wave?
High pitch
300
What is NOT a suggestion you would give to someone to decrease their risk of noise-induced hearing loss?
Answers may vary.
Example: stand as close as possible to the source of a loud noise
300
Sound also travels at different speeds depending on the temperature. Does sound travel faster on a hot day or a cold day?
Hot day
400
Noise-induced hearing loss occurs when what happens?
Exposure to sounds damage your hearing
400
Draw a high-volume, high-pitch sound wave.
400
Draw a quiet, low-pitch wave.
400
Generally, you can listen to a sound at 90 decibels for 8 hours before being at risk for noise-induced hearing loss. How long can you listen to a sound at 95 decibels?
4 hours
400
Though thunder and lightning occur at the same time, we see lightning before we hear thunder because...
The speed of sound is slower than the speed of light
500
How long do symptoms of noise-induced hearing loss last for?
They are permanent.
500
What does the amplitude of a sound wave look like if the volume is turned to zero?
A straight line
500
How does pitch affect the amplitude of a wave?
Pitch does not affect the amplitude of a wave.
500
What does NIHL stand for?
Noise-induced hearing loss
500
There are two main categories of waves: longitudinal and transverse. Which type of waves are sound waves?
Longitudinal
