Psychoacoustics and Auditory Neurology

Question 1 of 8

1

A sound wave is different to a light wave in that a sound wave is

Select one of the following:

  • 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.

Explanation

Question 2 of 8

1

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...

Select one of the following:

  • 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.

Explanation

Question 3 of 8

1

The external ear consists of the part on the outside of the head called the ________ plus the ________, which leads to the eardrum.

Select one of the following:

  • ossicle, oval window

  • pinna, ear canal

  • cochlea, auditory nerve

  • round window, middle canal

Explanation

Question 4 of 8

1

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 ____________.

Select one of the following:

  • localize sound

  • identify sound frequency

  • concentrate sound

  • provide information about head movement

Explanation

Question 5 of 8

1

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.

Select one of the following:

  • low-frequency, high-frequency

  • high-frequency, low-frequency

Explanation

Question 6 of 8

1

What are auditory objects?

Select one of the following:

  • The 'building blocks' of an auditory scene

  • Particles in a vacuum

  • Any object which produces a frequency <89 dB

  • It is not known

Explanation

Question 7 of 8

1

What is a fundamental frequency (F0)?

Select one of the following:

  • 20 cycles per millisecond

  • The lowest frequency produced oscillation of an object

  • Large amplitude waves

  • A harmonic frequency

Explanation

Question 8 of 8

1

Which one or more contribute to increased vocal AND facial attractiveness?

Select one of the following:

  • 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
