What you are physically measuring. You can not change it.
What is objective psychophysics
Goal is to see what CAN the listner hear
-Detection test: can you hear the signal or not (like the
elementary school hearing test)
-Discrimination test: Can you tell the ditterence betweent
What are the 3 ditterent tasks associated with objective
wo stimuli? (sound A is 10dB, sound B is 30db, can you tell
psychophysics
they are ditterent?)
-Recognition: can you process what you are hearing?
(hearing a word and repeating it back correctly)
What is subjective psychophysics What is the listener hearing. What DOES a listener hear
- Sensory scaling: measuring how much louder a com-
parison sound is from the standard using sones. (if the
comparasion of 1000Hz at 50dBs sounds twice as loud
than the standard at 1000Hz at 40dB then it would be 2
What are the 2 ditterent tasks for subjective psy-
sones louder)
chophysics?
-Matching: adjust the level of the comparison tone until
it matches the standard tone using phons (standard is
1000Hz at 40dB and is matched to 7000Hz at 50dB. The
match would be 7000Hz at 40 phons)
The smallest sound a person can detect frequency by
What is absolute threshold
frequency
playing a sound and slowly changing the dB amount until
what is ditterence threshold a person notices it has changed. The ditterence from start
to stop is their ditterence threshold.
the thresholds for signal detection in noise. Playing several
signal levels with background noise and seeing if the
listener can detect the signal at ditterent levels. Signal
What does the method of constant stimuli measure?
level varies each trial while the background noise stays the
same. The person determines if they heard the signal or
not

Relate a measure of listeners performance (how many
What is a psychometric function? times can they detect a signal) to a measure of the stimulus
(the stimulus intensity level)
thresholds are determined from the level of which the
stimulus is detected 50% of the time.
How are thresholds determined from a psychometric
function
- plotting results from method of constant stimuli and
seeing when they got 50% right from a certain dB level
Response bias (people wanna cheat)
-expectations: if you know what to expect, you will try to do
better
what is the limitation with the method of constant stimuli
-instructions: having clearer instructions makes you want
and the 3 examples
to do better ("Raise your hand when you hear a beep"
vs "Raise your hand when you're SURE you hear a
beep".)
-experience: doing something more than once will help
you do better the next time
What does the theory of singal detection address and Addresses response bias. Generates a method that can
how? produce a measure of sensitivity that is not influenced by
response bias. Some trials have signals and some do not
to catch the response bias
Hit: correctly noted that they heard the signal (said yes
correctly)
What is hit, miss, false alarm, and correct rejection? Miss: did not hear the signal (said no incorrectly)
False alarm: said yes when nothing was there (said yes
incorrectly)
Correct rejection: said no when there was no signal (said
no correctly)
minimum audible field is the minimum detectable level
what is the MAF procedure?
