lecture 19 (test 2) Flashcards
we experience intensity as
loudness
we experience frequency as
pitch
psychoacoustics is the
study of human hearing
Minimum Audible Field (MAF) Threshold
- present sounds sound to listeners from a speaker
- more natural
- sensitive to head movement
- very sensitive to localization and exam room
Minimum Audible Pressure (MAP) Threshold
- present sounds through headphones
- precisely controlled
- not sensitive to head movement
- not very natural
- eliminate some of the ears natural funneling and filtering abilities
lowest detection thresholds are ______ to ________-
2 000- 6 000 HZ
Terminal threshold
maximal sound pressures that humans can tolerate and then experience pain
The area between the minimal audibility curve and the terminal threshold is the _____
dynamic range
above threshold
suprathreshold
can feel low-frequency sounds because
the change in air pressure for an extended period of time (high-frequency changes are too fast to detect)
which; MAF of MAP produces higher thresholds
MAP
monaural stimulation thresholds are ______
higher by 6db
longer sounds are heard as being …
louder
masking
using a second sound to make the detection of another sound more difficult
what allows us to hear 2 000 Hz tone
masking
