Pregunta 1
Pregunta
A sound wave is different to a light wave in that a sound wave is
Respuesta
-
Produced by an oscillating object and a light wave is not.
-
Not capable of traveling through a vacuum.
-
Not capable of diffracting and a light wave is.
-
Capable of existing with a variety of frequencies and a light wave has a single frequency.
Pregunta 2
Pregunta
A sound wave is a pressure wave; regions of high (compressions) and low pressure (rarefactions) are established as the result of the vibrations of the sound source. These compressions and rarefactions result because sound...
Respuesta
-
is more dense than air and thus has more inertia, causing the bunching up of sound.
-
waves have a speed that is dependent only upon the properties of the medium.
-
is like all waves; it is able to bend into the regions of space behind obstacles.
-
is able to reflect off fixed ends and interfere with incident waves
-
vibrates longitudinally; the longitudinal movement of air produces pressure fluctuations.
Pregunta 3

The external ear consists of the part on the outside of the head called the ________ plus the ________, which leads to the eardrum.
Respuesta
-
ossicle, oval window
-
pinna, ear canal
-
cochlea, auditory nerve
-
round window, middle canal
Pregunta 4
Pregunta
The middle ear consists of a series of minuscule bones – the malleus, incus and stapes –connecting the eardrum to the cochlea. The primary function of the middle ear is to ____________.
Respuesta
-
localize sound
-
identify sound frequency
-
concentrate sound
-
provide information about head movement
Pregunta 5
Pregunta
The principle elements for converting sounds into neural activity are found on the basiliar membrane. This membrane vibrates in response to sound, with the apex displaced maximally by ______ sound, and the base displaced maximally by _______ sound.
Respuesta
-
low-frequency, high-frequency
-
high-frequency, low-frequency
Pregunta 6
Pregunta
What are auditory objects?
Respuesta
-
The 'building blocks' of an auditory scene
-
Particles in a vacuum
-
Any object which produces a frequency <89 dB
-
It is not known
Pregunta 7
Pregunta
What is a fundamental frequency (F0)?
Respuesta
-
20 cycles per millisecond
-
The lowest frequency produced oscillation of an object
-
Large amplitude waves
-
A harmonic frequency
Pregunta 8
Pregunta
Which one or more contribute to increased vocal AND facial attractiveness?
Respuesta
-
sexual dimorphism
-
an increased “distance” to the average voice/face
-
a decreased “distance” to the average voice/face
-
there is no physical indicator of vocal attractiveness
-
BOTH sexual dimorphism and decreased distance to average
