What are waves?
The high point of a transverse wave is called a
crest
The maximum distance the medium vibrates from the rest position of a wave is called the
amplitude
Sound is a disturbance that travels through a medium as a ________________wave.
Longitudinal
The ____________of a sound is the description of how high or low the sound seems to a person.
Pitch
This structure in the outer ear collects and directs sound waves into the ear.
Ear canal
A mechanical wave forms when a source of energy causes a medium to
vibrate
The distance between two corresponding parts of a wave is called the
wavelength
Sound waves can _______ around objects.
Bend or diffract
The pitch of a sound depends on the ____________ of the sound wave.
Frequency
This structure in the outer ear is a tightly stretched membrane that vibrates when sound waves hit it.
Eardrum
A low point of a transverse wave is called a
trough
The number of waves that pass a given point in a certain amount of time is called the
frequency
The speed of sound depends on what factors?
temperature
stiffness
density
_____________ describes your awareness of the energy of a sound.
Loudness
These are the three tiniest bones in the body that transmit sound waves in the middle ear.
Hammer
Anvil
Stirrup
An area where the coils are close together in a longitudinal wave is called
compression
Frequency is measured in
Hertz or Hz
The loudness of a sound depends on __________ and _____________.
Energy
Intensity
This snail shaped structure in the inner ear contains liquid and hair cells.
Cochlea
An area where the coils are spread out in a longitudinal wave is called
rarefaction
How far the wave travels in a given amount of time is called the
Speed
The change in frequency of a wave as its source moves in relation to an observer is called the
Doppler Effect
Messages are sent to the brain along the
auditory nerve
