PSYC-450 Exam Study Guide questions with |\ |\ |\ |\ |\ |\
answers
Pure Tones - CORRECT ANSWERS ✔✔a tune with pressure
|\ |\ |\ |\ |\ |\ |\ |\ |\
changes that can be described as a single sine wave
|\ |\ |\ |\ |\ |\ |\ |\ |\
Complex Tones - CORRECT ANSWERS ✔✔Made up of a
|\ |\ |\ |\ |\ |\ |\ |\ |\
bunch of different pure tones put together to create a
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
more complicated kind of sound
|\ |\ |\ |\
Periodic Sounds - CORRECT ANSWERS ✔✔A sound
|\ |\ |\ |\ |\ |\ |\
stimulus in which the pattern of pressure changes repeats
|\ |\ |\ |\ |\ |\ |\ |\
Fundamental frequency - CORRECT ANSWERS ✔✔the first |\ |\ |\ |\ |\ |\ |\
harmonic or fundamental of a complex tone, usually the
|\ |\ |\ |\ |\ |\ |\ |\ |\
lowest frequency in the frequency spectrum of a complex
|\ |\ |\ |\ |\ |\ |\ |\ |\
tone
Aperiodic Sounds - CORRECT ANSWERS ✔✔Sound waves
|\ |\ |\ |\ |\ |\ |\
that do not repeat
|\ |\ |\
Frequency - CORRECT ANSWERS ✔✔The number of times
|\ |\ |\ |\ |\ |\ |\ |\
per second that pressure changes of a sound stimulus
|\ |\ |\ |\ |\ |\ |\ |\ |\
repeat
,Pitch - CORRECT ANSWERS ✔✔The quality of sound,
|\ |\ |\ |\ |\ |\ |\ |\
ranging from low to high, that is most closely associated
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
with the frequency of a tone
|\ |\ |\ |\ |\
Amplitude - CORRECT ANSWERS ✔✔in the case of a
|\ |\ |\ |\ |\ |\ |\ |\ |\
repeating sound wave, such as the sine wave of a pure
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
tone, this represents the pressure difference between
|\ |\ |\ |\ |\ |\ |\
atmospheric pressure and the maximum pressure of the |\ |\ |\ |\ |\ |\ |\ |\
wave
Loudness - CORRECT ANSWERS ✔✔the perceptual quality
|\ |\ |\ |\ |\ |\ |\
most closely associated to the amplitude of an auditory
|\ |\ |\ |\ |\ |\ |\ |\ |\
stimulus
Timbre - CORRECT ANSWERS ✔✔the quality that
|\ |\ |\ |\ |\ |\ |\
distinguishes between two tones that sound different |\ |\ |\ |\ |\ |\ |\
even though they have the same pitch, loudness, and
|\ |\ |\ |\ |\ |\ |\ |\ |\
duration
What influences timbre? - CORRECT ANSWERS ✔✔Attack-
|\ |\ |\ |\ |\ |\ |\
the buildup of sound at the beginning of the tone
|\ |\ |\ |\ |\ |\ |\ |\ |\
Decay- the decrease in sound at the end of the tone
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
,first harmonic - CORRECT ANSWERS ✔✔pure tone with
|\ |\ |\ |\ |\ |\ |\ |\
frequency equal to the fundamental frequency |\ |\ |\ |\ |\
higher harmonics - CORRECT ANSWERS ✔✔the other
|\ |\ |\ |\ |\ |\ |\
components of a tone; frequencies are whole number |\ |\ |\ |\ |\ |\ |\ |\
multiples of the fundamental frequency |\ |\ |\ |\
human hearing range - CORRECT ANSWERS ✔✔2,000-
|\ |\ |\ |\ |\ |\
4,000 Hz |\
pinna - CORRECT ANSWERS ✔✔Structures that stick out
|\ |\ |\ |\ |\ |\ |\
Act as a funnel to capture the sound
|\ |\ |\ |\ |\ |\ |\
Help us localize sound
|\ |\ |\
auditory canal - CORRECT ANSWERS ✔✔Sound waves
|\ |\ |\ |\ |\ |\ |\
pass through |\
3 cm long
|\ |\
Acts like a barrier before we get to the inner ear
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
Hair & earwax
|\ |\
tympanic membrane (eardrum) - CORRECT ANSWERS |\ |\ |\ |\ |\ |\
✔✔Boundary between the outer ear and the inner ear |\ |\ |\ |\ |\ |\ |\ |\
Vibrates when the sounds come in contact with it
|\ |\ |\ |\ |\ |\ |\ |\
Transmits vibrations in the middle ear |\ |\ |\ |\ |\
, Ossicles - CORRECT ANSWERS ✔✔Middle ear bones
|\ |\ |\ |\ |\ |\
Malleus (hammer) |\
Incus (anvil) |\
Stapes (stirrup) |\
oval window - CORRECT ANSWERS ✔✔Boundary between
|\ |\ |\ |\ |\ |\ |\
the middle and inner ear
|\ |\ |\ |\
Stapes knocks on the oval window to send vibrations
|\ |\ |\ |\ |\ |\ |\ |\ |\
through
cochlea - CORRECT ANSWERS ✔✔The snail-shaped, liquid-
|\ |\ |\ |\ |\ |\
filled structure that contains
|\ |\ |\
the structures of the inner ear,
|\ |\ |\ |\ |\ |\
Scala vestibuli |\
Cochlear partition |\
Divides the space into two main sections
|\ |\ |\ |\ |\ |\
Scala tympani |\
organ of Corti - CORRECT ANSWERS ✔✔Hair cells-
|\ |\ |\ |\ |\ |\ |\ |\
receptors
Stereocilia- the part of the hair cells that respond to |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
sound waves/vibrations |\
