70%

100

what is the unit we use to quantify equal loudness contours?

phon scale

100

what determines the pitch we perceive in complex signals?

the fundamental frequency

100

what are the three main cues we use to localize sounds?

ITDs, ILDs, and spectral cues

200

what methods do we use to estimate the width of our auditory filters?

psychoacoustic tuning curves and notched noise method

200

a sound that is 70 phons is how many sones louder than a sound that is 40 phons?

8 sones

200

true or false: temporal theory and place theory together fully explain how we process pitch

false, we know the CANS plays a role because when we play dichotic stimuli we experience a different sound

200

spectral cues are helpful for localization in what plane?

vertical

300

in terms of frequency, what makes a masker most effective?

when the masker is similar in frequency to the target tone

300

what is the name of the concept that describes our brain summing loudness up until a certain duration

temporal integration


**BONUS 100 points: what is the cut off duration?**

300

what are harmonics?

multiples of the fundamental frequency 

300

using ITDs for localization is best for what frequencies? what about ILDs?

ITDs are best for low frequencies and ILDs are best for high frequencies

400
if i play 3 sounds, and i ask you which one sounded the same as the first sound, the second or the third, what interval and what alternative forced choice is this experiment set up as

3 interval 2 alternative forced choice 

400

fill in the blank: when the bandwidth of a sound increases, there is no increase in loudness if it is within the _________

critical band


beyond the critical band, we experience an increase in loudness

400

what are some limitations of place theory?

even when harmonics are present we only hear one pitch

the same place of stimulation can evoke different pitch perceptions (like when we modulate the amplitude of a signal)

400

what concept describes the phenomena that masking has less of an effect if it is in a different physical spot than our signal?

spatial release from masking

500

when creating a psychoacoustic tuning curve, what variable changes? what stays the same?

the frequency and level of your tone stays the same, while the masker frequency and level changes

500

what is loudness recruitment?

when the loss of OHCs results in a decreased dynamic range, but high level sounds still sound high in level so there is a rapid increase in loudness

500
if someone has damage to their OHCs, how does that affect pitch perception?

frequency selectivity is worse due to imprecise phase locking and broader auditory filters leading to poor pitch perception

500

how is lateralization different than localization

lateralization is "within your head" between ears, while localization is in the environment around you
