PSYC 230 UIUC Exam #2 Questions With
Correct Answers
Sound |stimulus |- |CORRECT |ANSWER✔✔-the |periodic |variations |in |air |pressure |traveling |out |
from |the |source
Sound |waves |- |CORRECT |ANSWER✔✔-the |waves |of |pressure |changes |that |occur |in |the |air |as |a
|function |of |the |vibration |of |a |source
Medium |of |sound |- |CORRECT |ANSWER✔✔-A |material |(solid, |liquid, |or |gas, |or |combination |of |
these) |through |which |a |wave |travels. |In |water, |sound |travels |4x |faster |than |it |does |through |air.
pure |tones |- |CORRECT |ANSWER✔✔-A |sound |wave |in |which |changes |in |air |pressure |follow |a |
sine |wave |pattern.
amplitude |- |CORRECT |ANSWER✔✔-the |difference |between |the |peak |and |the |baseline |of |a |
wave |(height |of |wave).
loudness |- |CORRECT |ANSWER✔✔-Perceptual |experience |of |amplitude
Loud |sounds |can |be |dangerous |- |CORRECT |ANSWER✔✔-Prolonged |contact |to |sounds |over |85 |
dB |can |eventually |cause |hearing |loss. |Sounds |louder |than |120 |dB |are |painful. |Sounds |louder |
than |130 |dB |will |generally |result |in |immediate |and |permanent |hearing |loss.
Frequency |- |CORRECT |ANSWER✔✔-The |number |of |cycles |in |a |sound |stimulus |that |occur |in |1 |
second
Pitch |- |CORRECT |ANSWER✔✔-The |subjective |experience |of |frequency
,what |unit |is |used |to |measure |sound |amplitude? |- |CORRECT |ANSWER✔✔-Hertz |(Hz)
What |is |the |hearing |range |of |humans |and |how |does |it |change |with |age? |- |CORRECT |
ANSWER✔✔-20-20,000 |Hz. |As |people |age, |hearing |in |the |highest |range |dissipates. |Lowest |
frequencies |tend |to |remain |stable |with |age.
Outer |ear |- |CORRECT |ANSWER✔✔-Pinna, |external |auditory |canal, |tympanic |membrane |
(eardrum)
Pinna |- |CORRECT |ANSWER✔✔-Collects |sound |and |funnels |it |into |the |auditory |canal
External |auditory |canal |- |CORRECT |ANSWER✔✔-conducts |sound |to |the |tympanic |membrane, |
amplifies |specific |sound |frequencies.
Tympanic |membrane |(eardrum) |- |CORRECT |ANSWER✔✔-Thin |elastic |sheet.
Middle |ear |- |CORRECT |ANSWER✔✔-Eustachian |tube
Tensor |tympani
Stapedius
Ossicles:
Malleus |(hammer)
Incus |(anvil)
Stapes |(stirrup)
Eustachian |tube |- |CORRECT |ANSWER✔✔-Connects |the |middle |ear |with |the |pharynx. |Equalizes
|air |pressure |on |either |side |of |the |eardrum
, Tensor |tympani |and |Stapedius |- |CORRECT |ANSWER✔✔-Muscles |attached |to |the |malleus |and |
stapes
Incus |(anvil) |- |CORRECT |ANSWER✔✔-The |middle |bone |which |is |connected |to |the |malleus |and |
hammer, |passes |vibrations |onto |the |stapes.
Ossicles |- |CORRECT |ANSWER✔✔-3 |small |bones |in |the |middle |ear |that |conduct |sound |
mechanically, |goal |is |to |amplify |sounds
Malleus |(hammer) |- |CORRECT |ANSWER✔✔-Affixed |to |the |tympanic |membrane |and |acts |on |
the |incus
Stapes |(stirrups) |- |CORRECT |ANSWER✔✔-Vibrates |against |oval |window |creating |pressure |
waves |leading |to |transduction |by |hair |cells |on |basilar |membrane |in |cochlea
Inner |ear |- |CORRECT |ANSWER✔✔-functions: |transduce |sound |into |a |neural |signal
Cochlea |- |CORRECT |ANSWER✔✔-Snail-shaped |structure |of |the |inner |ear |that |houses |the |hair |
cells |that |transduce |sound |into |a |neural |signal.
Tympanic |canal |- |CORRECT |ANSWER✔✔-One |of |three |fluid-filled |chambers |in |the |cochlea. |
Vibrations |travel |down |it.
Middle |canal |- |CORRECT |ANSWER✔✔-One |of |three |fluid-filled |passages |in |the |cochlea. |In |
between |the |tympanic |and |vestibular |canals.
Vestibular |canal |- |CORRECT |ANSWER✔✔-One |of |the |3 |fluid |filled |chambers |of |the |Cochlea. |
Vibrations |travel |down |it, |but |not |the |tympanic |canal.
