Factors that Affect Sound
100
This is broken when a whip is cracked
What is the sound barrier?
100
What sound is measured in
What is decibels?
100
The number of wavelengths in a sound wave
What is frequency?
100
Used by humans to perceive sound
What are ears?
100
This is determined by the amplitude of the sound wave
What is loudness?
200
100+ dB and an extremely high pitch are needed to break this
What is a wine glass?
200
Sound requires this to travel
What is a medium?
200
Determined by the frequency of the wave
What is pitch?
200

The smallest bones in the ear. 

What are the malleus, incus, and stapes?

200
One factor that affects sound and allows the sound to travel more easily the higher it is
What is temperature?
300
Sound cannot travel in this
What is space?
300
Sound reverberates best in this
What is a solid?
300

Large amplitude vibrations produced when the frequency of the applied force matches the natural frequency of receiver

What is resonance?

300

Acts as a funnel to concentrate the sound waves toward your middle and inner ear. Contains the ear flap and the ear canal.

What is the Auditory Ear Canal?

300

Audible Range of sound in Hz?

What is a 20Hz- 20,000 Hz?

400
The science of sound
What is acoustics?
400

343 m/s

What is the speed of sound at room temperature?

400
The distance a wave oscillates from its resting position
What is amplitude?
400
Made up of a cochlea, semicircular canals, and the auditory nerve.
What is the Inner Ear?
400

This is the human perception of how high or low a sound appears to be

What is pitch?

500
Hot air expanding fast enough to break the sound barrier
What is thunder?
500
Created when objects vibrate and travels through the compression and refraction of atoms
What are sound waves?
500
The shift in frequency of acoustic or electromagnetic radiation emitted by a source moving relative to an observer as perceived by the observer: the shift is to higher frequencies when the source approaches and to lower frequencies when it recedes.
What is the Doppler Effect?
500

Converts frequency, wavelength, and intensity into an electrical signal that is sent to the CNS.

What is the Cochlea?

500

Three factors that affect sound

What are temperature, medium, and pitch?
