  1. 1A sound wave is different to a light wave in that a sound wave is
    1. AProduced by an oscillating object and a light wave is not.
    2. BNot capable of traveling through a vacuum.
    3. CNot capable of diffracting and a light wave is.
    4. DCapable of existing with a variety of frequencies and a light wave has a single frequency.
  2. 2A 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...
    1. Ais more dense than air and thus has more inertia, causing the bunching up of sound.
    2. Bwaves have a speed that is dependent only upon the properties of the medium.
    3. Cis like all waves; it is able to bend into the regions of space behind obstacles.
    4. Dis able to reflect off fixed ends and interfere with incident waves
    5. Evibrates longitudinally; the longitudinal movement of air produces pressure fluctuations.
  3. 3The external ear consists of the part on the outside of the head called the ________ plus the ________, which leads to the eardrum.
    1. Aossicle, oval window
    2. Bpinna, ear canal
    3. Ccochlea, auditory nerve
    4. Dround window, middle canal
  4. 4The 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 ____________.
    1. Alocalize sound
    2. Bidentify sound frequency
    3. Cconcentrate sound
    4. Dprovide information about head movement
  5. 5The 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.
    1. Alow-frequency, high-frequency
    2. Bhigh-frequency, low-frequency
  6. 6What are auditory objects?
    1. AThe 'building blocks' of an auditory scene
    2. BParticles in a vacuum
    3. CAny object which produces a frequency <89 dB
    4. DIt is not known
  7. 7What is a fundamental frequency (F0)?
    1. A20 cycles per millisecond
    2. BThe lowest frequency produced oscillation of an object
    3. CLarge amplitude waves
    4. DA harmonic frequency
  8. 8Which one or more contribute to increased vocal AND facial attractiveness?
    1. Asexual dimorphism
    2. Ban increased “distance” to the average voice/face
    3. Ca decreased “distance” to the average voice/face
    4. Dthere is no physical indicator of vocal
      attractiveness
    5. EBOTH sexual dimorphism and decreased distance to average
